It did the job

Reviewed By Monty D (GRAND ISLAND, NE) Reviewed for a 2007 Ford Mustang —2/9/2016 4:55 AM

I used this tuner in my 2007 Ford Mustang GT. Loved that it let me set my tune and remove the speed limiter. NOTE* Make sure you update it before trying to install in your vehicle. I had to run the update twice to get my car to run correctly. More user error than any part on the tuner
