I have a 2000 ls block with a 99 gsr head. All internals are stock and evereything else is pretty much except for simple bolt ons. IM, I, H, E...etc. I have a street ports w/ 3 angle valve job but thats pretty much it. Im running a p-28 that was chipped over at Ericks Racing (Erick Aguilar) and after that it started running pretty damn rich. I got black shiot all over my bumper near my muffler. Am I losing alot of power? And how would I fix this? diff injectors? V-AFC do it? help!!!!!

 

get a vafc1 or 2 and lean out the fuel on a dyno. (have a tuner do this if you don't know how to yourself)

 

yeah i would say vafc could help you out

 

any of you guys know of a shop here in socal that can tune a V-AFC around the Los Angeles area?
