Is my bike running lean
It seems like its running fine but was just worried from the way auto tune was tuning it.
Exhaust is Bub side cutters 2 into 2
Intake Roland sands Turbine
controller PCV with auto tune
original map was for Bub 7 2 into 2
screaming eagle intake
Photos are as follows: Original cyclinder 1 fuel table, C1 Fuel table after excepting trim once, and current trim.

What you're looking at doesn't indicate lean or rich, it just shows +/- % adjustment to ECM fuel map, you just cant look at the RPM/TPS table and determine AFR. You need O2 feedback to know the actual AFR. I was under the impression that the PCV w/Autotune had O2 datalog capability. You need to look at an AFR log. Forget trying to read plugs as tune condition indicator, read the O2 sensors they are a little more accurate.

Like fabrik8r says your trims are showing adjustments. Each number equals .1 afr so no real big adjustments. What you need to see are your "desired" afr's. To address the popping put some 10's in the 0% column from 1500 rpm up and try it. Then adjust in increments of 5's and you should find a sweet spot.
