Could the dps be interfering with the wastegate/turbo? I know the wastegate actuator valve is located near the dps. Has anyone ran into wastegate problems with a dp install? And could that be the diagnostic for loss of power/"uneven" turbo intake sound?
Yes, it is possible that you accidentally bumped the wastegate actuator and it is stuck open right now, it happened on my car, but after getting back under there my friend and I were able to jiggle it back free and I haven't had an issue for over a year.

Just a thought but it does sound likely
