I just installed some mods on my 02 GTP. It has a k and n cold air intake, zzp wires, TB Spacer, 3 in DP, 180tstat, borla cat back and a OVERKILL tuned PCM. I also installed auto meter gauges and the air fuel ratio is running yellow (stoich) to red (LEAN) constantly. Since I'm new at this I just wanted to see if that is normal and if not what can I do to fix this?
