I have just purchased a 09.5 g8 gt and picked a superchips flashpaq f5 for and was wondering about the settings. If I leave it on superchips values which would be 100% tm off on upshifts I believe , will that cause damage ? It feels smoother at this setting to me. The problem I was having was the car felt like it was I guess you can say it felt like it was dragging like I had to keep applying throttle. Thanks for any replies.
