    Ok if you excuse my dumbass moment I can still offer a few suggestions.

    Go back into SD and tune the VE table. Use the narrowband fuel trims to do this. Set PE enable to 85kPa.

    MAF looks good. Need to log MAF Hz in order to make corrections. Don't touch VE since you're MAF-only right now. It's not dangerously far off.

    That's because setting SD on its own won't fix it. The tune is not squared away with incorrect injector data. I can look at the VE and see the shape and values are wrong. You have to understand...

    I know. Wrong engine configuration for stated goals, brand new to tuning, and wrong approach. Fortunately, there are pro's on here he can contact who would be well worth it.

    For the high IAT problem in traffic I'd have to see it. Could be related to higher BRAF than needed, for which I compensated.
