1994 K2500 Suburban 6.5 turbo.
Do most of you idle down to let the turbo cool after highway driving? I live a mile from the highway with back road speed being 45 mph and might hit 2 pounds of boost and figured that was good enough to cool down the turbo. If I come the other way home I have a 2 mile hill that runs about 8 pounds of boost so I idle it down for one minute after getting home. Lost a turbo years ago on a diesel from just shutting it down and dont want to do that again. Thanks
