hi i did have it so it was breathing to atmosphere and the problem was still there ive since reconnected to airbox
What i dont understand is it was spot on boosting to 20psi with no problems then had a front end crash and now its playing up since the repair the only thing we found is the actuator bracket must of bent as the rod was keeping the wastgate open all the time but all we done was adjust the rod and set it to 15psi and now got these problems im stumped to what it is thanks for advice
