Stock fuel pressure?

[dls93tsi]

does anyone know what the stock fuel pressure is set at. I just installed a 255lph and 550's.

I am soon going to get a www.dsmchips.com stage 3 w/ the 550 injector programming, but does anyone know how much fp th regulator will....regulate...with that setup...about...I didnt get to rewiring the fuel pump yet its freakin cold out once i can use a heated garage i will do that along with some other things.

I have another question to ask

When I wired the fuel pump up, i just wired it straight to the posts where the stock wires went, but I didnt put the little rubber boots on...the instructions say I can throw them away, but I always thought gas was a conductor

Wouldnt the gas take current away from the pump?

im sure his pressure is way higher than that now. can i ask why the hell youre rewiring a 255 without a afpr?

screw the chip for now and get a regulator. last thing you watn to do is wash out the damn rings.

Yes you need an aftermarket FPR, your fuel pressure is probably around 50, should be 38. Remember, a B&M "regulator" will not work either.

Is stock FP supposed to be 38 with the vac line on or off??

Are you running 550's and a 255 lph pump with no fuel control!?

You need a FPR. Stock 1g turbo mt is 37 psi. RTFM.
