I'm glad to hear the car is hitting redline faster. I had to delete the P0300 on mine, I just did it right off the bat because I ran the XP cam and that's what my tuner said to do, as well as ZZPoop.
if you add maf lb/min to your chart and multiply by 10 you can get a rough idea of how much power your car is making. mine peaked out at like 38 lb/mins.
edit: you could run a smaller gap now too, because you are running a lot of boost. and maybe try a set of NGK BR7EF to see how your car likes them. I think I ran mine at like 40 or 45.
