How are you tuned? Open source?

If you're tuned w/ a cobb, you should consider speed density to see if that is part of the problem. There is a setting on there where it blends the two so you dont have to retune right away, but it doesn't sounds like getting a modified tune is a problem for you.

Sure enough put a fuel pressure gauge on it and it is dropping from about 62psi back to 55psi in the upper RPM another problem...grrrreat.
No vacuum leak? What about bad MAP sensor? Not a common fail point but ... never know. Simple enough to check

Good luck!
