Ok so a co-worker was asking me about what would the best exhaust brake for his truck. Has an 07 5.9 auto. Only mods are Airdog 100, S&B intake, and Edge Juice w/ Attitude. I told him Pac Brake would probably be his best choice. Now, I am almost finished with my VGT swap on my 24v and I was thinking if it would be a cheaper solution to swap on a he351ve to his truck instead of spending the close to 2k to get a exhaust brake installed on his truck? The Fleece controller for the VGTs only goes up to 05 so is there something in the 06-07 trucks that makes is to where you dont need the controller? Or is it not even possible on these trucks? He tows alot and isnt going to go above the mods he has now.
