Fuel pressure Questions on 8psi
I'm running 8psi on a turbo setup and I'm running into fuel problems.
I hooked up a fuel pressure guage so I can monitor as I drive around. My stock idle low rpm driving is around 45 psi give or take. When I mash the gas in WOT sometimes it climbs to 50 sometimes 60 then falls to 30 sometimes to 20 Up in 4500 and higher rpm. It's different in pressure every time. Needless to say it's running lean
My setup is walbro 190hp
Supra 3.0 312cc injectors.
Running 8psi on t25
My questions
1.What fuel pressure scenarious SHOULD I be seeing after going WOT
2. What could be causing erratic fuel pressure. Stock fpr?
Thanks for any help!
