i think i am running rich or lean with my 3" pulley
well i took my car to the track last night and could not beat my previous time. the best i got was a 14.46 @99. i was expecting a 13 second run but dont know what happen. i can drive and my 60 foot was a 2.2. one of my friends said it may be running rich. it feels kinda of sluggish in the low rpms and doesnt accelerate as smoothly as my stock pulley. maybe the gm stage 1 reflash can fix this or it might be because of the humidity last night. if anyone can help me that would be great.
thanks
Brian

Also, do you have a MAF-T or a reflash done? If not, that's what the problem is. You can't just change the pulley.
You also need bigger fuel injectors. 42lb.ers

well i took my car to my friends boss who owns his own auto shop and look at my spark plugs and told me i was running lean because the plugs were turning a brown color unlike the NGK's which were goldish and also he said autolites are crappy plugs and am better off with the stock plugs. hes hooking my car up to a scanner tomorrow so we can do diagnostic checks like air fuel ratio and many other important things. jw so i know, what should our afr be at to run safely?
just a note he also said that the cold air intake is probably robbing me of roughly 5 hp and he said i am better off with the stock airbox which i will put back on tomorrow.

Did your friends boss say why he is of the opinion that the CAI is robbing power?
