Cummins West checked pressure on intercooler, I was told it held good at 30 lbs. They also checked all clamps, all were also good.
Ranger Smith: Cummins West is a distributor and repair facility.
Gasman 2: I'm thinking the same thing like electric or sensor not working correctly.
Hershey: It's kind of freaky how one time I start the engine, full boost and the next time it is not. The tech told me 35 lbs. of boost on the ISL Cummins is correct. You wouldn't think loosing 10 lbs. of boost would make that much difference, but from a standing start it won't hardly get going. Granted we always pull a race trailer weighing 6000 pounds.
