        5 Top Rated Questions

        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.

            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.

            Great Product!

            When i first got it i installed a preloaded tune with zero issues and it made a big difference! When i got more advanced i had a lot of questions and the people on the forum were an amazing help wit lots of knowledge. Highly recommend this if you're considering it. It really wakes your truck up

            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.

            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 run

            Does exactly what I wanted it to do increase in hp and torque plus turning off the AFM has increased my fuel mileage by .7 a gallon and without the delay when you want the power back I recommend this tuner to anyone with a 5.3

            dramatically improved my 2014 Silverado.

            way better. hasn't removed all of the lag in the accelerator. thought I would remove the afm. left it on I kind of like it and mileage went down when I did. averaging about 19-20 now

            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.
