Hello everyone! Maybe I can find right advice about this issue. I have 2015 T270 expedite truck, paccar px9/cummins ISL9 350hp. 5000 miles ago def/egr was off and 1000 miles ago dpf filter was drilled. I noticed on the road today - probably turbocharger making unusual whistling noise when taking off gas pedal. Whistle only in motion, while idle everything ok. Besides it feels little bit loss of power uphill (empty/loaded). What it need to check first before I’ll go to rebuild a turbocharger? Thanks
