Innovative Aggressive tune vs. Xtreme street tune

Ok I got my Xstreet tune in January, and have been using it since, before that I ran the aggressive street tune all the time, when I switched over to the X street, I really didn't notice that much difference, except for my EGT's rising a lot faster, anyone that has run both tunes did you notice a big difference between the 2? or should I have gone with the race?

I just run the race tune everyday and the tow tune when I tow anything significant. I got the extreme street also but the only difference is the torque converteris locked from 3 through 5 gears and the race has the torque converter locked from 1 through 5. theres a few tenths difference on the 1/4

There is def a big difference between the 2. Are your boost levels the same on both tunes? If everything looks right just contact Eric and he will try and fix it!! (Great Customer Service!!!) Might just be a corrupt file and he should send you another

my TC don't lock, when I get it into 5th I can keep it there if I'm easy on the throttle, but if I try and pass some one and get on it a little too fast it will down shift, same if Im lugging a hill. what kind of boost are you guys getting on the X tune? the highest I've seen mine was 29psi

Do you not want it to down shift? If so why? You want to bring the rpm's back up to get in the hp curve. Some trucks are different with the boost levels though. Mine hits right around 26psi and 29 max. The aggr tune is set a little more for the tq curve instead of the hp curve and if you still think there is a difference go back to the aggr tune and you will def notice a difference since you have been on the Xstreet for awhile
