Just Awesome!
Let’s be honest, the car comes with a good amount of horsepower from the factory, but this tune wakes the car up like no other. Much improved throttle response, horsepower, and no loss in fuel mileage. If you’re even thinking about a tune, Steeda is the way to go.

Even more fun
I already had the Steeda intake and a Corsa exhaust so decided to add the tune. Really woke the car up, especially around 5k it really seems to hit. Also Ive notice while in 6th less of a need to down shift. MPG has improved as well. All around, well worth the money.

Tuning Done Right
Got this from Steeda and started with a 93 Octane custom tune. Ran great and it was nice being able to take the rev limiter up a few hundred RPM. Things got more serious as I put a ported 2018 Intake on my 6 speed manual 2015 Mustang GT. I wanted to keep the CMCVs active and Steeda honored my request. I set the rev limiter at 7600rpm when loading the tune. I finally got a chance to see what a difference it would make from the original intake and tune when I took it to the strip. Picked up a solid 4 mph on the top end with a 12.3 @ 116mph on a mediocre all season radial. Steeda did this tune right. I had a guy in the lane next to me with the exact same mods on his 2015 but he was running an E85 Lund tune while mine is a 93 octane tune. It was all he could do to barely stay in front of me. The beauty of this tune for life is seeing how each mod affects performance. Steeda is a first rate company!

91 Tune with B/O 2015 GT
Extremely easy to program. Used the hotspot on my phone as wifi for programming. Took all of 10 minutes to run the program. The power gains weren't instant, I have driven daily my 2015 GT and it's been just over 2 weeks. The exhaust tone is different, WAY better throttle response, stronger pulls in the top end as well. Very very please with the tune and how simple/small the BDX tuner is!
