Are you talking about the electric fuel pump? Yes you can increase the fuel pump pressure. If you're talking about altering the fuel INJECTION then you need an SCT tuner to reprogram the PCM and TCM to do it correctly.

You can up the fuel pressure by "shimming" the fuel pressure regulator spring located on the secondary fuel filter bowl where all the fuel lines tie in. Use a regular "BB" like you'd shoot in a BB gun or go to a bobcat dealership and get part# 6592105 which is a hardened "BB" that's a tweak bigger and will put you at about 65psi. The BEST way to do the fuel pressure is with an ITP regulated return system. You'll still get a pressure drop but it will recover much faster than the stock system and you have the benefit of fuel flow all the way through your heads. Running the programs you're running you really need a RR fuel system and an upgraded pump--IMHO.

I'm gonna send you a PM with a link since it's someplace else and I don't want to get in trouble with the mods.

the gain of shimming the regulator isnt enough to make it worthwhile in my opinion,every vehicle responds differently to this mod , some say its great others dont see a difference ,and your really not gaining that much , wait and get the returnless system

Exactly Scott, and some even say it gives them cold weather starting problems. It's a patch at best and no substitute for a good RR system and/or pump upgrade.

Speaking of pump upgrades--Scott do you know of a replacement pump for the stock location that's an upgrade for the stock pump that's not an arm and a leg like the FASS?
