I have a 2011 6.7 with a H&S XRT Pro Tuned to Hot, all delets dun with just replacement pipe turbo back, S&B cold air, Silncer ring cut out of turbo.
At normal driving the truck runs great but when I really put my foot in it, it hesatates and makes a weird noise and vibration for a few seconds and then rolls smoke out and runs like crazy. Just wondering what that vibration and noise could be. And Is it a bad thing to run the truck on Hot all the time. Any thoughts would be great!
