At high boost getting an overboost, car hesitates until it goes into limp mode , I'm pretty sure it's a vacuum leak, checked both bov and stock diverter valves looks OK to me, but happens with both sometime after 11 psi , is there anyway to do a vacuum leak test in the shop ? besides just looking at the hoses ? Maybe it's my wastegate actuators ? How can I check ? This drives me $#@!ing crazy !!!!! :mad0259::confused2Click here to enlarge tried IT WITH NEW OLD AND EVEN OLDER MAPS so I doubt the tune is causing it
