SCT X4 Power Flash Programmer 2015-2017 is rated 4.5 out of 5 by 10.
Rated 5 out of 5 by from Great Product Big horsepower gains when combined with JLT Intake and exhaust. I'm 100% satisfied with the purchase

Rated 1 out of 5 by from Not as great as I expected! From the description on CJ it states that you can choose from a performance or Eco tune but when I was trying to upload the files I wasn't given that option except to choose the 5.0 as the next step? My car drove better using Pedal Commander with no tune and since I have the 93 Octane on the SCT stock tune the gear changes too quickly and doesn't feel right, I didn't even see the gear ratio option to change like I saw on CJ's video??? The pick up with the tune is noticeable on the mid-high end but not well balanced for every day driving. My 2 options are to go with a Bama tune or go back to stock and after paying $600CAD this tuner isn't cheap so with Bama tunes for life it will cost me another $200CAD+ to have it done but will have to as I cannot live with this SCT tune on a daily driven car!

Rated 5 out of 5 by from Easy, BIG power gain Incredibly easy! Hook it up to the internet to update, hook it up to the car to identify it, back to the internet to get custom tunes, then back to the car. Took a little while, but they tell you that and it worked perfectly. Used with JLT CAI and the custom 93 octane tune and HUGE power gain.

Rated 5 out of 5 by from Having a Lil problem I installed my sct x4 tune on my 15 Mustang gt but I'm having a Lil problem when i release my foot off the gas or press the break my vehicle jerks the only then I change was the octane to my gas 93. Pulse I plan on getting me a JLT intake next week

Rated 5 out of 5 by from works perfectly with jlt cai I bought this tuner because of the cai I was installing. The 2016 mustang gt/cs required a tune to run the jlt cai. The whole process went nice and smooth.

Product Questions

Hey there i have an American imported 2016 auto mustang and i live in United Arab Emirates, and the fuel octane over here is 98 so will i get more hp then the 91 octane on the auto? If yes how much can it be?

Asked by: Alexander2121
You will have slight gains over 91 or 93 found in the United States, but nothing major. The main benefits will just be consistency and your fuel being less prone to knock or pre-detonation.

I have a stock 2017 V6, will I have to swtich to premium fuel, or can I stay with regular fuel? What kind of HP gains can I see with regular compared to premium fuel?

Asked by: Tom81
You can choose what octane you plan on running. If you want to see noticeable gains, go with at least 91 Octane. But for the most performance, you will need 93 Octane Fuel.
