limp mode? boost leak?
srry overlooked ur first post im having the same problem did u try unhooking your n75 valve and clear codes and then run it thats the only way my will run good but i do get codes but i scan mine with a snap on scanner
when you tried that did u atleast get one good shift? when i mean with out the n75 valve i just mean have it in the intake and hookes up to turbo and wastegate just unplug the harness just to clearify
