High HPOP Pressure
Ok hope someone might be able to help me out. I just put a Stealth SRP 1.1 HPOP pump on my truck (because old one only maintained 2400psi at WOT).
The pump works great.
All throttle positions appear to be fine looking at my gauge and how it acts.
However, when at WOT it goes to 4000psi and maintains 4000psi without dropping a bit.
It has a fairly new ford ipr and icp sensor (2 months old). I installed a new backpressure sensor when I swapped the pump.
Does someone know why it would maintain 4000 psi now?
