Default Tuning O2s ???

okay, i've autotapped my car several times and under WOT runs, i don't seem to get any KR (i know i should be happy:-) even though my B1S1 &B2S1 readings are around .84x-.89x but usually they seem closer to the .85x-.86x range which i thought is kind of lean. Also, my Ltrims are always in the 4-9% range usually 6 or 7% which to me would mean that the car is running lean and the comp is trying to compensate for it. So my question is: should i get a MAFT to get my Ltrims down or am i okay and should be happy and not worry because i'm not getting any KR? Or, should i get it to mess around with the POT settings and maybe leave the WOT alone? TIA <img border="0" alt="[Camaro]" title="" src="graemlins/camaro.gif" />

You are running lean and I would think about either MAFT or LS1 edit to fix this. The best way to really fix this is a dyno and wideband O2's and adjust with LS1 edit
