HPOP Pressure

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.


Thanks!

It's not necessarily toast yet, just not healthy enough to keep up with tunes. Get an aftermarket HPOP, it will make a huge difference. My old modded 17 was down to 1800 before I replaced it with a SRP1, it's so much more fun to drive now.

Cant afford an SRP1, would a T-500 keep up with split shot injectors ok?

Factory splits or stage 1 should be no problem. Your best bet is to talk to Joey at TE, he will be able to tell you exactly what it can handle.
