Ok got turbo kit on finally and now getting ready to take a get a dyno tune. I called them this morning to set up a time and they were asking me what king of fuel pump, injectors,MAF Im running and then asked me if I had a adjustable fuel pressure regulator. I've looked and cant find one that is specifically for a 2004 mustang gt. Is there a way to get a universal one and hook it up or does anyone know where I can find one. Any help would be great as this is now holding me up from getting done. Thanks!
