2005 Alpine Coach, 36FDSS, Cummins ISL 400 Pegasus / WRV
8.8 L / 538 CID (Yes, it says 8.8 not 8.3 or 8.9) Engine No. 46429471
My turbo has stopped boosting – almost.
When working correctly the SilverLeaf showed up to 23 psi & maybe higher.
Just going down the road the boost dropped to 6 – 8 psi and it will barely climb a slight grade.
I have no idea why this happened. I lifted the bed and looked around and found a 90 degree black rubber & canvas elbow with a small slit and a hole I can put my finger thru.
I can’t see all around the elbow at this time. Could this be the problem? I would be inclined to think this would reduce performance but not that much. Does anyone know where I can buy that elbow?
