  • wastegate rattle

    right i have just had a garret conversion on my astra new exhaust stage 4 mapping etc but i seem to be having a rattle coming from my wastegate so i checked the wastegate and the wastegate flap was loose i could move it about but im pretty sure that this is supposed to be setup closed and not loose so i took the slack off of it at the same time not putting extra any pressure on it now it is overboosting an extra 5 psi does the map need adjusting to suit this???

                      sounds good to me, yeah engine should be fine, as it sounds like your running low boost so internals should be ok...
