well, i convinced the wife that i need hptuners, since i have three chevy's and will be able to tune all three myself then. the sub is actually fine with the tune i have from allen. but i am constantly changing the silvy and would like to be able to tune on the TBSS. i have heard a tune REALLY wakes them up. all i have is a CAI but taking out some TM and firming up the shifts would probably feel great.
my problem is i dont know if i can actually do the tuning. i have some experience with tuning, but it was on dsm's with dsmlink.
