Maybe this is why it seems to wait till the RPMs build before it can use the pressure of the ESC. I'll be testing this out as well as several slightly modified tunes this weekend to see what difference it makes.

Be really careful that you don't lean out at high RPMs under boost when you're messing with that table. You're effectively changing port injector fueling for the entire rev range. 2 PSI of boost at 2000 RPM is not the same as 2 PSI of boost at 7000 RPM in terms of how the ECU provides fueling.
