I installed their tune at 33k and am still happy with it at 414k. Big fan of the turbo brake option. Its very reassuring descending a long grade with TT pushing you and makes it easy to control speed with only occasional assistance from the TBC if and when you are towing heavy. (over 6k down a 6 percent) In fact despite towing TTs my original brakes went 293k. Always received excellent service as well. Just don't tell that one guy. He has some kind of inferiority complex with them and trys to undermine them and the Ecodiesel in general at every turn. Hope he don't come in this thread and read this I will be attacked relentlessly.
Thanks for telling us your story. Do you have any pics of your truck and whats been done to it?
