and has stock wires on it. any ideas
 
You'll need a fuel pressure gage of some sort. It's a rising rate FPR, right? You'll need to know what DSM's run stock for fuel pressure, start the car, pull the vacuum line off the FPR, and set it to stock (or what ever you tune for, but I doubt your going that route just now). Then re-connect the vacuum and go.
 
T don't know much about the fpr, but ive got mycar set up somewhat like yours and my thing is that I think you should get 650 injectors or bigger. cause once you get everything on and the boost turned up your car might go into fuel cut. my buddies got 550s and a 16g and he cant get on it without it shuting of the fuel due to lack of.
