I looked at some logs using a snap-on scanner today on my car. No codes present. I did a WOT blast and had the scantool log. My O2's were in the 970 to 980 range, 0 to 1 degree of knock retard across the rpm range and timing seemed to hover around 22 to 23 degrees. My L-trims never went above or below +/- 3....My questions is why is the car running so rich??? I also logged some cruising runs and the L-trims hover right around 0. The car has a lid, stock screened MAF, Mac headers and custom 2.5" offroad Y with flowmaster collector and 3" hooker catback. It ran rich on the dyno only making 310rwhp and bellowing black smoke. Fuel pressure is 61psi at idle with the large NOS inline pump. Could this be the problem? '99 Z28 M6 stock internals
