Default Fuel Pressure Regulator - 07-09-2018, 12:57 PM

I have the stage 2 bucketless from Fuel It and I love it. I run the VTT Stage 1 turbos and I also love them. I did not get the upgraded fuel lines yet and I have seen a few people ask about the need to upgrade the fuel lines and a FP regulator.

My question is what FP regulator do you get? Is this only needed when upgrading the fuel lines? Is this needed for PI?

Any info would be helpful.

An upgraded FPR is only needed for high HP port injected applications.

Thanks Steve. When you say high HP with PI are you saying if I was to swap to a single turbo and run PI anything over 600whp would need a FPR? Can you give me an idea on the power level?
