I installed the performance tune in my 20007 chevy sliverado witithe 5.3L. It shifts extremly firmly when ipunch the throttle down and have to get off the throttle. If i can punch it and just go i seems to shift fine. is firm shifting going to cause a problem?

No, it will not be a problem...have you tried lowering the line pressure in the tunes?

Thanks

nope just used the tune that was in the predator. I am kinda sketched out about adjusting things I have no clue about.
