Hello,
I have a 2002 z28 with the ls1 and a auto trans ,the car already has the ls6 intake . After adding the intercooled sts turbo kit with about 6 pounds of boost I have alot of problems even a knock sensor code tonight. The kit came with 42# per hour injectors and ngk tr6 v power plugs gapped to .035,it also has the msd boost a pump I have already cleaned out the cats that were plugged. But I still have very poor performance and I am showing miss & hiss in the data veiwer. I have been working with rick at sts but I am scared to do any more tunning at this point due to the problems I am haveing. The programmer is a U7198.
