this past weekend i did the EBPV delete on my truck. Had an oil leak so i figured i might as well get rid of it. bought the EBPV delete pedestal and then just removed the butterfly and welded up the hole. Got it all reassembled and then test drove it. Its got a louder WHOOOOSH now when i let off the throttle from the turbo. It's just different. Is this sound normal after an EBPV delete??
