wierd noise from turbo

[messticle]

i recently installed 4 inch exhaust and downpipe. My intake has not arrived yet but i couldnt wait try the truck with the exhaust and an Edge programmer. truck runs great on stage 1 of the edge but now when i let off the throttle there is a tremendous air noise, either blowing or sucking I dont know, coming from the turbo area and through the exhaust pipe. did i blow something up? will it go away with the intake? what about the ebpv valve? any help? thanks

You can unplug the the EBPV and see if your trouble clears. The connector is kinda under the turbo on the driver side.

check to make sure the down pipe is ot rubbing the fire wall. mine was and was very loud inside the cab , used a prybar and deadblow hammer, to fix problem.
