Hey, guys. Adam here with americantrucks.com. Today, we're taking a look at and installing the Diablosport inTune i3 Tuner, fitting all '14 to '16 5.3-Liter Silverado 1500s. Now, if you're the owner of that gen 5.3 Silverado, you might be looking to pick up a pre-loaded tuner, otherwise known as a canned tuner in order to pick up some really easy gains right off the rip for a lot of different driving scenarios.Now this particular tuner here from Diablosport does come with a couple of different tunes fitting all types of octane levels, '87, '91 and '93, fitting your economy class or street tuned, which is gonna be your '87 all the way up to your race or Diablo tune for the '93 octane levels. Now, of course, you can also adjust different parameters on the tuner device itself, including your axle ratio, your tire size, air/fuel ratio, wide open throttle timing, fuel timing, all types of different things. You can just adjust right here in the advanced tune section or of course you can do an easy tune and just do right off the bat with their pre-loaded selections there.If you want to pick this up for yourself that comes in just around 400 bucks. And again, it's a very easy tuner to use. It's got a 2.8-inch high-res touchscreen here which is a lot smaller than a smartphone. As you can see, can hold it up to my phone here, it's extremely small compared to something like this. Now, of course, using this in your hand, it is extremely comfortable. It's got a nice rubber grip here, so if you're trying to tune your truck while doing some routine maintenance on it, it's very grippy so you're not gonna be slipping out of your hands. It's also got a nice little chrome trim here just give it some accent and color. The touchscreen itself is extremely easy to use and extremely responsive. If you're trying to use this on the fly here in the truck, you could just plug it right into your OBD-2 port and use it on the fly extremely easy. There's no load times, there's no extreme waiting periods or lags, it's a pretty seamless process.Now, in addition to the 2.8 screen, you're gonna get a lot of other features in here other than just tuning the device. It also got Wi-Fi software updates, this has support for both windows on PC and iOS on Mac users as well, so that's gonna be a plus. This is gonna carry a DTC code reader, otherwise known as a diagnostic trouble code reader or your check engine light. That light comes on your dashboard, plug this thing into your OBD-2 port, it will read the code, give you the code and a description of it to tell you what's going on and what's wrong. When it comes time to fixing it, you can obviously just go right back into your device and clear the code as well, get that check engine light off the dashboard. It also has a data logging feature of course which you can work with your tuner with. You can plug it right into your laptop there and diagnostically see what's going on with your car to update your tunes or your custom tunes on the fly as well, that's a huge feature to have on your device.Now finally, when it comes to actually tuning your truck, it's extremely simple. One out of three wrenches on our difficulty meter here. I'm definitely gonna say it takes about 15 to 20 minutes at the most. It's as easy as following directions on the screen and setting your parameters to your personal preference if you don't want to use one of those pre-loaded settings.Now with that said, I want to show you what we did. We obviously put this thing on the Dyno on our own 5.3-liter Silverado. We made a baseline number, so we're gonna check that out. We're also gonna upload our 93 tune or our race tune on here to see what the maximum amount of potential that we can expect outta this thing is. So without further ado, let's head over to the Dyno and see how our truck perform.Now, taking a look at our Dyno runs here for our '16 Silverado, we did our baseline run, of course, 87 octane, same tires before and after just to get the most accurate results. Now, our factory baseline and walked away with 253 horsepower and about 290-foot-pounds of torque at the rear wheels, not too shabby. Of course, then we uploaded our Diablosport i3 tune, 87 octane, and ran it again and came away with 265 horsepower and about 296-foot-pounds of torque at the rear wheels, good for a gain of about 13 horsepower and about six torque at the rear wheels. Now, pretty good peak gains, but it's really the curve gains that gets to be a little bit more impressive. We're looking at about 13 horsepower, 13-foot-pounds of torque at right around 4,500 RPMs which is that sweet spot. It's low to mid-range, that's where you want some more of that torque to come in handy. And keep in mind guys, this is on a completely bone stock vehicle. Consistent 13 horsepower in the double digits for curve gains. I like the results on our '16.Getting into the Diablosport inTune i3 tuner installed on your Silverado, your 5.3-liter Silverado, is extremely easy. Flashing your truck is a very, very simple process, you'll follow onscreen instructions and I'm gonna show you how to do that. First thing's first, to get this thing turned on, you're gonna plug it into your OBD-2 port under the dashboard, so let's get into it.Right when you plug it into your OBD-2 port, it's gonna turn on, you're going to get a long i3 waiting screen. But the next thing you'll see is pretty much just a disclaimer. The Diablo inTune is designed to increase vehicle performance, fuel economy, never use this in vehicle operation. So you agree, hit Yes.Moving on, you'll be greeted with three different options on the home screen for the i3 tuner, tune vehicle, scan tune, and settings. The big, big option here is the tune vehicle. So once you get into that, it'll load up a few of the options that you'll have for your custom tune or your pre-loaded tuned depending on which route you're going to take with your Silverado.Once you get into the tune vehicle menu, you'll be given easy tune, advanced tune and restore backup. Moving into advanced tune's menu, you'll get the install the standard tune, install a custom tune or modify your parameters. Now, modifying parameters we're not gonna get into in this but if you wanted to get specific with how it's being tuned from your device, you can go ahead and do so. Custom tune, again, we're not working with today but if you had a custom tune that is where you would select it. Installing a standard tune in the advanced menu gives you a little bit more options. You can install your Diablo tune or the race tune which is for 93 octane. You get the 87 octane tune, an MPG booster for guys looking for the best fuel economy. You can modify a stock tune or have the skip control unit option. So we're gonna get back out of the advanced tune option, we're gonna go straight for the easy tune.Easy tune gives you four very straightforward selections: 93, 91, 87 octane and MPG boost again for the economy guys. Now, because we have 87 in the tank right now, we're going to make an 87 octane tune pole [SP]. So let's hit 87 octane. Again, 87 and select it with a yes. Install your standard tune. At this point, you're given a couple of options, you can tune for transmission firmness or hard shifting tunes, you can modify a stock tune. We don't have any of that, so we're gonna skip that control unit. Do you want to change tire size? No, we're working with stock tires today. Gear ratio? No, stock gears. Remove the speed limiter? No, we want to keep all the settings are the same. Now it says the i3 will read a vehicle backup so that we can go back to the stock option, and we definitely want to do that, so we're gonna hit yes. So reading the backup for your original tune is a really beneficial step in this process because it will save your stock tune to the device. So after you do tune it to 87, 91, or 93 whatever tune you decide to pick, if you ever want it to go back to your stock tune you have that saved on the device, you can revert to stock at any time.All right, so it'll come up 87 octane tune, do you want to install right after downloading and installing your backup to the device? You want to hit yes. Now, do you want to apply all of the selected options you've changed before? We didn't actually change anything, so we're gonna still go with yes just because we want to make sure it's on the same page. It will turn traction control off on your dashboard, you'll see that. It'll say service a couple of things just because it's messing with your ECM. So in the tune device, while it's making these adjustments and updates to your ECM it's going to make these adjustments to your dashboard.At some point during the downloading process or the flashing process it will tell you to turn your ignition off, so you just want to flip the key back and hit continue on the device. Turn it back on and hit continue. Then go back off again, and go on. Tune is complete. You can unplug the tool and start driving the vehicle.Let's go into the settings real quick just so we can see what that's about. You do get Wi-Fi configuration, so whenever you need to make updates to the device itself you can do it via Wi-Fi and there's also a port at the top here to plug into a laptop. You get analog inputs setup, sound and display, might come in handy here. See if we can actually turn the beeping down. Here you go. From there you can adjust brightness and volume of the device, it does make a little beeping noise every time you touch it, so some of you guys out there like myself might want to turn that off. From there, advanced options which we can go into here you can check for updates, like I said, via Wi-Fi or you can plug it in. You also get a tech support menu or if you have a custom tune that's an option down there as well. We did not have a custom tune today, we're working with the pre-loaded tunes, which we'll see in just a little bit. Going back to the home screen you get this nice back arrow up there, makes it very simple to go backwards.Scan tool we'll look at next, which actually you have to put your vehicle in the run position but not actually start, so I'm gonna turn that on. So once you get into the scan tool menu with your vehicle in the on position but not fully running, you'll be given three options: show trouble codes, clear trouble codes, data logging. Trouble codes is pretty obvious, right? You get a check engine light, not sure what it's about. You can plug the Diablosport into your OBD-2 port and you can read what that trouble code is giving you, what's throwing the code, what the issue is, and you can take it from there, makes your life a lot easier. You can clear the trouble code as well. So if your oil light comes on or whatever the case may be, tire monitor, tire pressure sensor monitor, once you fix the issue, you can clear your trouble codes here if you need to. Data logging again, guys with custom tunes who are looking to get the most out of their performance here working with your custom tuner, you're gonna want to take advantage of the data logging feature just to keep track of your performance and see what needs to be changed.All right, guys, with all of that wrapped up, that's gonna end my review and install and Dyno performance of the Diablosport inTune i3 Tuner, fitting all '14 to '16 5.3-Liter Silverados. You can get yours right here at americantrucks.com.

Simple enough to install. Just follow easy on-screen directions. Went with 87 octane canned tune and firm shift. So far love it, shifts good, seems more responsive on throttle. Gas mileage - unknown. Word of advice on tire size - use tire height if updating. I used sidewall first on a set of 35/12.5/20 and speedo was 30 mph off. Went back and put 34" height and now spot on according to GPS.Helpful (1)

Definitely feel the power increase!
Awesome product. It was a quick easy install and you can notice the power increase. On the 5.3l I thought the pedal was not as responsive as my 5.7l ram was but it had really good mileage. This tuner gives me that responsiveness and mpg I was looking for.Helpful (1)

2016 5.3 Silverado
I just installed the i 3 tuner on my truck I like that I can increase throttle sensitivity and turn the dod off with it .I can’t say I really noticed any performance gain I’m going to return it to stock tune run on my local performance shops dyno then do a run with the 93 to see the gains. im running the 93 tune with the throttle sensitivity turned up to 10 will see how it performs in the long runHelpful (2)

Improve performance and horsepower
With so many choices, it is hard to decide which one to purchase. I was not looking for on-the-fly adjustments, but I did want the ability to data log. This tuner provided me with options that I was looking for at the price point offered here. The same tuner was found elsewhere for $100 or more. I was able to install the ECM and TCM tunes in just a matter of minutes. Installed on the tuner was 5 preset Dyno tested tunes. I am currently testing the Diablo Tune. What I am liking up to this point, the how the vehicle no longer feels like it falls on its face in stop and go traffic. What I liked about this particular brand and model was the support available for the product. You can easily get custom tunes installed from any local dyno tuner for your custom setup. The Sierra/Silverado forums can direct you on the best direction to go. Another feature that I really liked, is you do not have to buy additional tuners to program a different vehicle. As long as Diablosport supports the vehicle you are trying to tune, you can unlock license spots with just a phone call.Helpful (19)
will this disable the afm?
The Diablosport inTune i3 Tuner will not disable your Silverados AFM System (Air Fuel Management).
Will this tuner work with the JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob installed?
A custom tune and tuner like the Diablosport inTune i3 Tuner would be able to control throttle response, meaning there would be no need to have the JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob installed. Installing both a tuner and the JMS PedalMAX Drive By Wire Throttle Enhancement Device w/ Control Knob can result in error codes and the vehicle going into limp mode in extreme cases.
Does this allow you to adjust the speed at which the AFM kicks in or even allow you to turn it on or off?
This will only allow you to disable/enable AFM.
Will this get rid of v4 mode?
By reading the other reviews people ask about the AFM and some answers say yes and some say no, not to specific on if it's about the automatic fuel management system or the air fuel management. I wanna disable the automatic fuel management system (v4 mode) on my 2014 Silverado. Will this do that?
This tuner's features will vary from truck to truck. It would be recommended to look on Diablosport website for specific features.
This tuner is able to adjust the speed limiter.
The code reader will work other vehicles as long as that car is a supporting car to the tuner.
Unfortunately this tuner will not work with a 2018 5.3L Silverado.
This device is not compatible with GMC models, it is compatible with 14-16 5.3L Silverado 1500 models.
The Diablosport inTune i3 Tuner will not disable your Silverdos AFM System (Air FuelManagement).
