any ideas why my rail pressure does this parked at idle? My rail pressure is also dipping to sub 1500psi during WOT(20psi 93oct) as well as slight dips in Ipfp under 72psi.
I’m also seeing timing corrections, log attached.
feeling like it can be tired hpfp, tired Ipfp, or a leaky injector(s)
MHD custom tune
FBO MMP
stage 2 bucket Ipfp (about 40-50k mi)
index 12s(about 40-50k mi)
original hpfp (about way too many miles)
fresh LP/HP fuel sensors, MAP sens, plugs, coils, 02s, walnut blast etc etc

Trims are up there, you're out of fuel is my take.

Is it a 450lpfp in the bucket? Try switching it out for a 535. Might fix your issue.

Yes, it's a 450, noted...curious if it'd be a direct swap into the bucket. Haven't there been issues with the ekpm overheating if I'm not mistaken?
