Default New logs stage 2 +

Fuel psi 1750-1900 all the way (autotechs all the way). Little bit of KR on the first run, still under 1. AFR looks dead on,
boost is dead on 19psi from 3-4.5k, 18 from 5k-redline.

Virt dyno says 277hp/320trq for 3rd gear log 1. So I am right on track for 295-300whp when I add the downpipe.

rfinkle2 hey finkle, how are my afrs? Commanded is 11.850, they fluctuate from 11.6 all the way to 12.06.

yeah you are. I would get a few logs and check to see where it is consistently and repeatedly off in the same spot by the same amount, then adjust those areas to hit target if you are concerned. Essentially, apply the multiplier value (logged AFR/commanded AFR) at that specific region of the MAF scale.

Yeah, unforunately it seems to be different every time. W/e I am within my +/-2% so I guess I won't worry about it.
