Do you have any longevity reports about your speedbrake for a 6.0? I've got a '07 6.0 and pull a 14k trailer. I just had by turbo go out and replaced at 92k miles and the dealer said, would you really want to subject this turbo to even more stress and increase the failure potential more? That is a good question, and while I want the speedbrake, I don't want to replace the turbo on my own dime even sooner. How many miles have you seen these go without negatively affecting a turbo? Thanks, David.
