On hills, keep the tach up around 2000 rpms to keep the fan blowing as much air as possible across the radiator and keep the turbo boost as low as possible if the engine temperature starts climbing. Past about 12-14 lbs of boost will really start adding heat loading on a long steep grade.
Yeah, Ron gave me a tutorial and how to use them. I was very concerned on having the past above 15 and the pyrometer over 600 but not sure if I did it correctly because for brief periods of time, while climbing, psi went above 20 and didn't overheat.
What I'm working on now is not to release the gas pedal when I want to slow down because going back to the right gas pedal position without making the entire coach shake is a fine art!
