APR seems to be very picky with.what components I fit, I'd say car performed better with original actuator. Also fitted n75j valve some months ago kept going into limp mode, also.tried n75h from mates car did same as soon as boost it 22-23psi limp mode. Have bought a race n75 of someone on here couple weeks back but not turned up yet ( be named and shamed if don't get money back). But going put standard actuator back on next week, it was making same boost as forge One anyway. Bloody cars eh!!!!
