I have been suspecting that my hpop is getting weak but haven't been able to confirm until I used my buddies AE tonight. I didn't get the data logging but we did several WOT runs from 35-80mph. On every occasion my pressure would spike to 2,400-2,700 but immediately drop to 1,900 with an 85% duty cycle and stay there till I let off the throttle. This was with my PHP chip set to 80hp daily driver. I assuming this means that my pump is pretty much toast, but I wanted to check with you guys first.
