It was very easy to use and made a huge difference in the acceleration and shifting on my 09 G8 GT.

I am overall very impressed with the tunes. It took me about a week working with support to get the tuner working on my truck. The support staff was great to work with. The tuner is showing some MPG gains and it let me correct my spedo. The tuner also seems to hve added a bit of low endo power which I like. I dont tow but I do have the truck lived 3" with 33's.
