Hey guys so I just got this 2007 lbz Duramax and I put a new y bridge in it and got ride of the ETR then the bridge gasket failed and I needed a new turbo so I took the cab off and new turbo, new vein position sensor and fixed the y bridge and got the truck all back to gether and the truck is only building 12 pounds boost and has no power and just blows excessive black smoke and the turbo will start to shutter when it’s floored and the turbo still won’t circulate
