It did the job
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
Jury is still out
I loaded the 91 octane tune. This tune seemed to add pep in several RPM ranges that were lacking. Maybe my expectations were too high. One downfall is the mileage. It has dropped but I have not calculated the difference yet. One improvement needed is the shift point from 1st to 2nd gear. It is too quick and rough. I would like to try the custom tunes available after running this tune for several more weeks. Is the tuner is worth the cost? The jury is still out on that question.
