Ok so my sct tuner just came in today so first thing I did was hook it up. Since I have 87 octane in my tank right now I only tired the 87 preformance tune. Now I know it's gonna sound dumb and I know I'm probably just crazy but I feel like my accerlation is a little faster not alot but a little. It feels like I'm getting to 50-60 faster now. The only way I can be sure is down at the strip Sunday. I wish I would have put 93 octane as the race tune buy after it was all said and done I order the 91 octane and guess what where I am at here in Texas very few gas stations carry 91 they are all 87,89,93. Is there anyway I can change that. Don't I just go to the AM sute and tell them I need the 93 race tune? But anyways am I the only one that thinks I felt some gain without going to a dyno or the track?
