What disk am i supposed to use in the sfmu and waht pressures should i be looking at. I got three disks with my SFMU, the shop is having problems with the car running and i think it the fuel. Any suggestions, i have the 30lb injectors and the SFMU setup.

Turbonetics 60-1/Portfueler/etc!!!!!

How much boost are you running? There's a graph in the instructions of the S-FMU as to what disk/spring to use. I'm running 6psi and use the small dark spring and the disk that was already in there.

I plan on 7-8 psi. it is already installed but my friends at the shop are not sure about the sfmu. I am heading down to Tampa in about 4 hrs to pick it up and find out try and correct the sfmu and make sure it is setup correctly. I got the instructions, so i should just go by that.
