        How much HP and torque gain with this tuner? Does it eliminate the speed limit?

        • On a stock Mustang you could gain 15-20 HP, however the speed limit would require a custom tune to manipulate.

            5 2015 GT - brian2015gt

            Love it

            It's a night and day difference between having this little device and not having it. I've got a borla exhaust cat back and it's tuner on a 93 octane tune. I raise my rev limiter a few hundred RPMs. And it really woke the car up. Have a 2015 GT performance pack car with 6-speed manual transmission and my only regret is I didn't buy tuner sooner. Updated through Wi-Fi in my garage. I love this little thing and I would recommend it to anybody.

            1 2018 GT - TimGT

            No custom tunes. Only works with stock

            This is an expensive piece with awful support from SCT. They tell you to find a dealer for custom tunes. I have a 2018 GT with only the Roush Cold air kit, and no tune for it... I am very disappointed since they make is seem like its easy to get tunes and upload to the device. It's anything but that. Avoid this product

            Better than I expected.

            I'm new to this retail tuning but the BDX has loaded and swapped tunes with no problems. Very impressed.

            Wrong CAI program!

            Overall, this worked. However, I have (and was specified when purchased) CandL CAI. The only option in the programmer was for JLT. Also, the programmer hung up on the last step. I finally just unplugged it and crossed my fingers! Luckily, I was successful.

            This tuner is really fast and easy to use. Also the cloud makes it so easy to use. The thing I would say is certain dtc codes keep coming back everytime I clear them. Other than that this tuner Is beast.

            Does Not Work!!!!!

            Will not work on a 2019 mustang gt. Even though it says it will. I called SCT and was told they have nothing available for the 2019 yet.

            Easy to Use and Effective

            The canned 93 octane tune drlivered increased throttle response, more robust shift points, and even increased the miles per gallon from 24 to 28 on a 6 hour drive with and without.
