The timing seems to be the only problem i see. Your boost curve looks pretty smooth and shouldnt be the problem Without the maf you car ran a little more deg advance and why it was a little faster before 4.5k. However it did jump up and down all the way to about 5k where as w/ the maf it looked like it should.

 

I was on a different timing map.. I was running T9 and T8.. now im on T5
