Could I be running lean?
now im trying to get into prom tuning... reading all i can about it,
my question is, could my car be running lean or hurting anything if i don't have an air pump or EGR hooked up? i know these things can be tuned out but i don't have the means yet...

I didn't run lean after removing the air pump and egr. I don't see where either would affect the afr but even if it did the o2 would pick up on it and the ecm would adjust.
