1. You have a 2g MAS, so the massive adjustments in the MAF Comp table are a bit excessive. Also, this is causing your AFRatioEst to become incorrect and not match up with the LC-1 reading. You can use this to help get it dialed in, which shouldn't take much adjustment.

2. Take a look at this to adjust your TPS - v3tpsadj [ECMTuning - wiki]

3. I'd put back some of the timing you took away, especially around 3500-4000 RPMs. This will help smooth out your timing curve and give you back more timing. Unless you end up knocking, then pull it back out.

4. I might also pull some fuel out from 3000-4500 RPM to smooth out the LC-1 reading around 11:1.

I did put some timing back in and I got 1.1 to 1.4 counts of knock. I was just trying to get my afr's set were I read they should be about 12.5! So I pulled alot of full out and got my AFR's around 11.7 to 12.6 with only a couple little blimps of .4 knock!
