I just got a Hyper Pack tuner for my truck and I would like to know the optimum shifting points for my 2002 4wd 5.3 yukon. I just had the programmer, corvette servo, boost valve, and accumulator installed on my truck today and I love the way it shifts!!!! But when the truck shifts out of first into second gear the belt slips??? The transmission is firm but not bad enough for my gf to complain about it..
The programer shows each of the gears and the incriments are +-100 Rpms at a time over stock shifting points. IThe program has a setting to increase the firmness of transmission but this is not on Btw and it is set on 93 performance tune. Any help would be appreciated.
