right.. fitted uprated manifold, gutted cat and fitted hks actuator a week ago now it sounds like the manifold is blowing from somewhere. stripped it back down and put loctite copper gasket sealant on but it still sounds exactly the same. sounds like a tractor, as if it is missfiring.. but its not any ideas? any tips for finding where its blowing? also after setting boost with actuator it seems to take forever to reach it peak. put foot down and i just get lag lag lagggg lag boost well above 4000 rpm before it starts to rise as if its opening wastegate way too early.
