ok, me and my buddy have been working on his car, 2003 Mustang GT AUTO, all day, he had 4.10's installed and we installed his LM2 catback, MAC CAI, C&L TB/plenum, and loaded the diablo tune and played with the shift points etc. Our other friend comes over with his 99' GT AUTO and were like "ok lets run em and see what a difference it made" He has a 99'GT Auto with a LM2 catback and a BBK CAI, THATS IT!!!! and beat my modded friend by 2-3 cars! It wasnt even a contest! WHAT THE HELL HAPPENED????? we went from a dig and when that didnt work from a roll and the result was the same everytime! Were trying to find out whats wrong, any ideas? maybe the predator messed something up? PLEASE HELP US!

Install the stock tune again and give it a try.

I am and so are many other members, firm believers AGAINST canned tunes. They suck.

Now with the stock tune in, you can still do shift points correct and you only need 87 gas? its been a long time since i messed with my tuner

+1, on de tuning it. did you tune it yourself or load a preset tune

we loaded the canned diablo tune and then just played with the shift points
