So i have a 2001 supercharged max running the FMU that stillen had with the kit which is the disc type FPR and the AUX pump under the hood. Im replacing the FPR its has on it now with the AEM one.

Now my question is what pressure do i set it to? I'm running 3.125 pulley (11lbs).

I have done some research and see people adjust the pressure between 37 and 43. what is my ideal number for my set up?

BTW I'm running stock MAF and injectors

About 43 (stock) with the vacuum hose off.

 

Cool - thanks dude. I'm installing it now, I'll take pics when I'm done.

 

Ok so just to update this - i put in the FPR in with no problems. took me about 2hours. so initially i adjusted it to 43psi with the vac hose off and with it on went down to 37psi . So at this point i took it out to do a little "street tune" to get my Air/Fuel to a safe area.

first time out i was at 12.9 - to lean for my comfort under boost. I was raising the pressure 1 -2 psi at a time till i finally got it between 11.0 and 11.3 under boost and the thing feels awesome under WOT. finally pressure was set to 43.5 psi with the vac on.
