Hey ringram. Your problem would be the oversensitive KR it will pull timing aggresively even on high octane fuel. Your IAT will be high aswell due to the MAF being heatsoaked.
By the way my problems running mafless have been fixed. No more surging between gears, unsteady idle or problematic starts. Switching off spark smoothing solved this.
Car runs very smooth now. very responsive and snappy with more power everywhere over the maf tune.
