I have recently installed a CTSC and have decided to go the route of bigger injectors instead of using the FMU. I have an emanage blue and just purchased RC550cc injectors. Im running 7psi and the walbro 255 lph fuel pump.

Do i need an adjustable FPR since i want to run stock fuel pressure.

Will i have any issue with the stock fuel pressure regulator running the walbro pump?

 

No bro you should be percectly fine with your setup. Good luck!

 

I agree with TRBOKEV, all is well w/ the stock FPR

 

Cool thanks guys. Saves me a bit... put that towards some useful gauges.

 

Is the stock fpr 1:1? if i hit it with boost will it rise 7psi at wot?

 

Yes stock FPR is 1:1. Yes if you hit boost fuel pressure will rise in conjunction with your boost. I run 14psi on stock FPR just fine.

 

Perfect. Thanks everyone.
