Take a look at the pic with OEM and Mallory side by side. Now imagine the adjustment screw being up about 1/4" more (factory setting @ ~45 psi).
Now, go under your hood and feel the room that exists between the FPR and the bottom of the upper. There isn't much! While you are in there, try to imagine how you'll get tools in there (the TB flange shields your access even more) to tweak the fuel pressure to where you want it. I doubt it could be made to work, but I also wouldn't mind being proven wrong.
