So I did some more pulls with the advanced timing making a point to do it in warmer temps as to confirm that the increase was not due to lower IAT's in the cooler air. Although I did not do so before mucking up my MAF scale using one of those home made maf rescaleing apps. Results below.
I guess 1 more degree of advance summoned up a couple more ponies to the wheels confirmed, even with the wonky fuel trims and AFR's.
Heres what the 2 best pulls from each session and the best pull from the OTS tune looks like on the same graph.
I'll probably add another degree of advance in the same spots as I did earlier and see what happens, but only after I get my MAF scale sorted out first.
