Boost issue
2008 Cobalt SS
ZZP FMIC
ZZP CAI
Injen Charge pipes
ZZP tune
Magen Racing CDP
GMS1
6,000 trouble free miles since modding it, halfway to work it felt sluggish and I noticed it wouldn’t boost at all. Cut the car off and back on, made boost the rest of the way to work. On lunch I made it a mile before I lost boost again, restarted the car and it built boost for another mile or so, hit 24 PSI like normal then it proceeded to fall on its face. Wastegate rod is good, no codes, fuel trims hover around 2-3% and the MAF is brand new.
