Good tunes, challenging software
2012 F150 3.5 EcoBoost bone stock other than this tune- I've had this only a couple days. I had some challenges getting the device updater software to work. In fairness it worked better once I made some updates to my computer. But I haven't had issues with any other software previously with that same computer. In the meantime while trying to update the tuner firmware before the software was working consistently, the device got stuck. I had to call SCT and it took about an hour to get a rep. Once I had him, he was able to unlock the device and update the firmware in about 10 minutes. I loaded the 87 Octane tune. I noticed subtle yet very obvious performance gains. Most noticeably stronger and more smooth lowend torque. This made driving easier, more satisfying, and most importantly improved how the cruise control performs over rolling hills which is one of my major beefs with the stock. There is no more lagging, sagging, slowing down etc. Overall I'm pretty impressed with performance given that I'm using the lowest tune. I haven't driven it enough to give a legit MPG comment. But so far, about 50 miles, it seems about the same. This combined with the performance improvement of the lowest tune is reason enough for me to give this a 5 star rating.... BUT...I ordered an MPT tune and it was delivered very timely. I loaded it to the device with seemingly no problem. When I went to my truck and plugged it in, I now have the same communication error that stuck the device before. So now I have to commit another 2 hours of time between 9-6 EST M-F to get this resolved with SCT. I have no doubt that they will fix it once I get a rep. But for the time I've spent getting this tuner to work, I feel like they owe me money. And by the way I'm very capable with computers and know what to expect. Thus I'm giving an overall rating of 4 stars. But, I would say the tunes themselves are worthy of a 5 for a relatively easy and cheap bang for the buck performance upgrade. And I'm looking very forward to trying out the higher tunes.Helpful (0)

I expect more for $400. This is less.
I guess everyone leaving high marks for this tuner has very little expectations for their money. Or they don't care. I went and purchased this tuner not knowing much about tuners because it is portrayed as "the one" to get. I am very dissatisfied with it. For $400 I expect multiple part upgrade options and to be able to fine tune the wheel size to get my speedometer dead on. Neither exist in this tuner. There is 1 option for a cold air intake and 2 options for exhaust for my 2013 3.5 Ecoboost FX4. That is it. I don't care about making the transmission shift later or adjusting computer controlled spark. Also the display is small and if you wanted to mount it, it looks oddly shaped and is hard to read. I rather have a nice rectangular display than the shape of a paddle sitting on my dash. I am just not happy at all with this poor purchase decision.Helpful (5)

Once was able to load the device with the updated software this unit is amazing. I will say this, I might have thought twice if I would have known up front that I needed a Windows computer to manage my SCT Tuner. I had to call everyone I knew to see if I could use thier computer to install the updated software. The unit was on back order, you would think that it would have been loaded with up to date software. Also on the shipping container there is a port in the box where you can plug in to update. This was crazy and the only sore sport I had with this unit. Once installed I was blowen away.Helpful (4)

2014 F150 4x4
Overall very satisfied with the truck's performance with the SCT X4 preloaded tune. I had changed to 275/65/R20 tires and needed to recalibrated speedometer, but decided to go with a performance tuner as a bonus. Definitely better performance and noticeably better shifting. Fuel performance seems slightly better, but really haven't give it a chance yet. Not as straight forward to install as I had issues updating, but the helpdesk created a fix quickly and I was back on track to install.Helpful (6)
I have a 2013 f150 EcoBoost. I drive around 110 miles a day. I'm currently looking to improve my fuel mileage, about 17mpg, without hurting performance. The truck is 4wd, has 3.55 axles, and tire size is 265/75/18. What kind of mpg improvements could I expect to see? Does this tuner have any programs already on it?, and can it stay connected to the truck, or does it need to be disconnected once tune is loaded? Sorry about all the questions, just wanting to make sure it will do what I'm looking for before i make a purchase. Thanks.
The SCT SF4/X4 Power Flash Tuner will include SCT's preloaded strategy tunes. This can be left connected to monitor various PIDs, and will provide minor mpg gains. typically less than 1 mpg.
Does this tuner have a delete option for catalytic converters,
The SCT SF4/X4 Power Flash Tuner does not offer a delete feature for catalytic converters as this is regulated by the EPA (Environmental Protection Agency).
I own a Ford f150 2013 all stick no mods on it would this work for a my truck. I'm a new to tuners just want to know if I should get this or not for my truck
The SCT SF4/X4 Power Flash Tuner will work with your 2013 Ford F150, Some gainsover stock performance can be gained even without modification.
I have a 2013 F150 Limited Edition truck that comes with the 22" rims. Will this tune differ for my truck from the other F150's and will it change my speedometer any? I see that under all of the adjustment options it states that they do not apply to "all" models. How do I know what is compatible with my truck?
There is a lot of information needed for a proper tune. Wheel size and tire size are two pieces of information needed for a proper tune. By tuning, adjustments can be made to factor in the differences in your F150. Please call our in-house tuners at 8882269764 and they would be happy to assist you with any other questions. Our hours of operation are from 9 am until 7 pm, Monday through Saturday.
Have a daily commuter that hauls a 5500 lb boat and trailer a few times a year. Am installing a Roush 3" exhaust and adding a cold air intake. Are there existing tunes loaded that would work for me? Would like a tune using 87 and 91 octane. Does this unit have to remain connected after the tune is installed? Can I purchase a tune for a 2010 Mustang GT and use this same unit to install it?
The SCT SF4/X4 Power Flash Tuner will be able to tune for your modifications. When installing the tunes, you will be able to select from octane ratings for your truck. This device can only tune one vehicle at a time, and will be VIN locked to that vehicle unless it is returned to stock. This can be switched between vehicles a total of 5 times before it becomes locked and an Unlock from SCT is required to use on a new vehicle.
Yes, MPT Tunes can be loaded on to your SCT X4. You will just need to purchase them separately.
We estimate that with no modifications, a gain of 12 RWHP / 13 RWTQ with an 87 Octane tune at the curve and a gain of 23 RWHP / 25 RWTQ with a 93 Octane tune at the curse. Of course these numbers will vary with the amount of modifications that are done to your truck.
