How do you know? Hey,
I have Mac Mids and a catted y pipe, slp loudmouth 1, o2 sims, and a K and N FIPK, is there any simple way to tell if I am running too lean? I dont really want to spend the money on getting my PCM reprogrammed if I dont have to. Also, the Z has Bosch plugs and wires, should I swap the plugs with NGKs? Thanks guys!

A friend with a WBO2 is a much more accurate way of telling. Or...find a dyno day this spring, ask them to hook up the shop's WBO2, and make a couple pulls to see where you're at.
