Turbo noise

Chicago, IL

#1 Oct 13, 2011
I have a 2004.5 Cummins with SuperChips programmer and Stage 2 CAI. I've notice now that on a medium pull from 50 to 60 mph that when I let offend throttle I hear a "whoosh whoosh whoosh" What is that noise and can it hurt anything?

I have a 300 HP Cummins powering my motor home. It's a 2003 with only 50,000 miles. It is currently in the shop receiving it's third (3) turbo. Does anyone else have this problem
