Nope, not throwing any codes.
It seems to be a turbo issue since the intake and power is off. I have a bov and I can barley hear it now.
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?
