Hey guys I have 94 Camaro lt1. I did 58mm tb, long tube headers, cai ported heads, 503cam. My? is should I be worried that the car idles bad and has a slow throttle reponce. Did not get a tune yet looking to use pcm forless. And I have no engine light on nor stored code thank lou

U need a tune with the new cam and headers. Ive been told this by several people on here. There are some good threads about tuning as well if ur a do it your selfer .
Im pretty sure once u get her tuned, she'll run better.

with all that extra chatter from the bigger cam, and of course the now louder exhaust, i would get an LT4 KM in the pcm. will help the pcm eliminate false knock, specially when it gets tuned my bryan from pcmforless.com i got a great tune with my bolt ons lt1 a couple years ago
