Always go back to the area you were working. You most likely took out the 3000 pipe and other ic pipes, so start there. Pay close attention to the TB to 3000 pipe cupler. Other than that, I would close the gap on the plugs a tad more

I dont know if you have considered, but the stock CT doesn't hold boost at higher rpms. I set my MBC to ~1bar and it always dropped off at redline to not much more than 10psi
