MP8 Exhaust Brake Valve Lash

Just replaced #1 injector and cup on 2013 MP 8. Truck starts and runs just fine until turbo spools up and get a very noticeable knocking sound in Number one cylinder. Cut injector out noise goes away. Also when engine is running at higher rpm's the knock lessens and pretty much is gone. Any idea's ?
