Help-Turbo Boost

Follow up: So I got into Cummins Bridgeway for service to check out the potential boost problem. It was time for a lube, oil and filters change on the engine and genset anyways. They hooked it up to computer and and the coach showed no signs of boost problem or loss of power of any kind. They did through inspection find an air filter somewhat constricted and needing to be changed, so they changed that. There opinion is electrical, either ground or just a bad gauge as suggested by you all. So we are leaving this morning for 12 day trip to the Adirondacks for some hiking,sight-seeing and must needed relaxing. Time to build some more memories. I will track down the gauge or electrical problem when we return home. I just wanted to give a thanks to everyone who responded to the problem with there suggestions and knowledge. I really appreciate it. Safe travels to everyone and have a good day!!
