Fuel Pressure Regulator

[exotic performance]

Hey guys im having a problem. When my car starts to cilmb in rmp's my car is hitting fuel cut off at like 5500rmp's. Could this be caused because im running the stock fuel rail with stock fuel pressure regulator?

I don't see why that would be a problem...there are alot of guys running more power than you with no problems. I think MWR is still using the stock rail and regulator with 400+ whp.

What kind of engine management are you using? Sounds like a problem with wiring... If its not the PFC, everything soldered into place correctly? That would be the first thing I would check.

Im using the PFC. I have 550cc injectors with 255lph walbro fuel pump.

I think Bing or someone had a similar problem to this only at around 3000rpm. I think it was something to do with the injectors not being installed correctly or something.

Check your injector connections. My injector connections weren't connecting properly due the vibration of my engine.

You stock FPR should definatly be able to push enough fuel with the walbro and 550cc injectors.
