I've been running a "tow w/ jake brake " for a year. I love it. It just shuts the VGT vanes on deceleration. It helps a bunch towing in hilly country and it can't be beat towing in the mountains in the winter. Load it in the truck and give it a try. If you don't like it then take it out. I can tell you this, it'll excercise your turbo vanes and help keep them from sticking.
