Believe you me you will see a difference from the stock tune

 

I don't know man. Just got it today and i went right to the 93 tune and loaded that. Honestly right now I feel it was a waste of almost $400. I don't know what to expect but I took it on the bypass an seemed to feel the same. So I don't know.

 

Well I am not sure about you but here is my Update: Today I finally was able to empty my tank of 87 octane and install my new Brenspeed 91 race tune, WOW......................... HOLY HOLY S### I floored it and almost slid off the road in to the other lane, talk about a lot of extra power I didnt know I had here, smooth firm shifts and down right dig fast, not to shabby for for my auto, it is amazing this is the same car I had a week ago , talk about put you back in your seat , now I know what the head rests are for . I didnt know how much more fun it is to drive with all the extra giddy up it Thanks Brenspeed !!!!

 

Cool man. I'm glad it worked for you. Maybe mine did work. I'll have to go back to stock then back to tune and do some testing
