u can run 10 psi max on a std chip, take out the ecu unscrew the cover then unscrew the board and see if the chip has a aftermarket manufactuers name on it, tbh ur best bet is to get it set up properly by someone who knows what there doin and dont touch the bleed valve unless u wanna re do ur headgasket and anything else that will proberbly blow up if u wind the bleed valve out

cheers kev
