Could also be fuel pressure. If you can measure pressure at the fuel rail, it can give you indication. Not sure what your pressure should be but if you hit the accelerator (go wide open), the pressure shouldn't fluctuate by much. See if you can get it scanned.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
