Yes I'm running the CP-E HPFP. And no, it's not an AP thing, you'll need an upgraded pump regardless of what tuning solution you have if you have a failing pump. The higher boost you run, the greater the importance of having good pressure. Cobb says no less than 1200 PSI at WOT is safe, but people on the forums say no less than 1600PSI.
The ATR does have beta fuel pump tables where you can raise the commanded fuel pressure. But since I see over 17XX PSI at WOT, I've left the tables alone.
