Default wierd wastegate noise

when my external wastegate opens, the noise is really wierd sounding like detonation almost....its not detonation cause the ecu reads no knock. it doesnt sound like the normal air wooshing. is that normal for some wastegates depending on where its mounted and stuff?

normal. you have an open dump. when the wastegate opens engine exhaust is heard with no muffling whatsoever. the sound of open dumps can really vary froim car to car. some are tolerable some are not. some like the sound some dont.

Dane I know when I was running my open dump setup it would make a weird noise when I was at partial throttle and the wastegate was opening and closing really quick.
Are you referring to this being at wide open throttle with the noise your hearing?
