Sounds like the FMU has gone bad. You might try disconnecting the vac/boost line (don't get into boost, and watch air/fuel while driving) and see if your fuel pressure remains more consistent.
Stinker's right though. The Paxton system's a bandaid. For me it's going to be like a bandaid on a mortal wound!
Time to talk to UGR. They will set you up for whatever power level you're running at.
actually its pretty simple, well kinda
I may be a tad different than most(huh magine that
) but I like one fuel pump, one set of lines, and one regulator, kinda old school.
but that way I never have to worry about one of the pumps going out, and having a lean condition, or wiring up a hobb switch.
But I personally think we need to get SLH motorsports or Justin one to fab us up some fuel rails, nothing expensive or elaborate, jsut where they will work with an fittings.
then all ya got is to run the fuel lines to the pressure regulator , pump and tank.
only problem is connecting to the tank, in your own way.
now if you put a fuel pump on the frame rail, it will be noisy, i have gotten used to mine.
I do know UGR is getting there machinist to fab up a new tank insert to mount pumps in the tank with correct fittings, dont knwo what they will cost, but looked nice, this would give no noise, keep the pumps cool aslo..
now the prob with my pump is it gets hot, eventually it WILL go out, but at the same time I want have to drop the tank to replace it
