Can you export the graph to a table? I can't help out at all, especially with an image that small.

40 counts of knock is unheard of. I believe you either need a knock sensor or new lifters.

My FWD had a bad knock sensor when I first bought it, and it was doing the same thing. As soon as I'd roll the throttle on around 2300-2500, it would pick up injector pulse or lifter noise and MAX OUT the knock count. At 40 counts, it was pulling so much timing that it felt like a non-turbo.

May need a knock sensor also I would hurry, and do that rewire.A 2g maf on 510's will be on the lean side.

I would turn to boost down just a little bit just to be on the safe side too. Dont want to run too lean or anything

I was thinking that 510s would be a bit lean @17psi, but am still learning so I wasn't sure. 550s/560s would solve that problem.
