So I'm tuning the beast. I'm noticing with 94 octane pump gas I'm getting no knock at all and O2's are just slightly fat at 820. The cars top end has really woken up - it can really spin them hard through first and second now. But I noticed the BLM were down near 108 at idle - is this too rich? what kind of problems can this cause? What is the best way to fix this? Should I lower FP some more until it looks good at idle and then check O2@WOT and boost levels and KR? What is the best way to approach this? I need to reset my IAC, can this have anything to do with a rich idle?
