Yeah but add power to it and forget it. I heard tuning on the 6l is a nightmare, if it isn't perfect it won't last whatsoever.

I saw a 2020 High Country Duramax yesterday with factory wheels. How did that ever get passed by anybody at GM? Those are the ugliest wheels I've ever seen.

Wrong thread. We have a 2020 duramax thread for that. This one is for the gasser
