Re: why am i so lean?????? Are you getting any knock?My 02's on A tap read lean too,.79-.85 at WOT with no knock.I dyno'd with a wideband and A/F showed 12.8-1.So the stock 02 sensors can not be trusted.

Re: why am i so lean?????? I agree the stock o2 sensors should be ignored at wot, they are totally inaccurate. Timing is different for the various years. Timing should drop at WOT when compared with cruising, especially at max torque (4400-4800 rpm for stock car).
