Whats the manual say? I'd be willing to bet there is no mention of turbo cool down. I can't even find mention of turbo cool down for my '11 2500HD with Duramax. Apparently GM doesn't think its necessary.
my '07 Ram with the Cummins had a section of the manual dedicated to turbo cool down. Even though GM doesn't think its necessary,I still follow the cool down times I used with my Cummins.
