I cranked my truck this AM and started to work. I had no brakes and could not turn the steering wheel. I had my programmer in Performance mode and then re-programed to stock. After re-programing everything started working. Has anyone heard of this before?
It is an issue with your brake booster, has nothing to do with the tuning. There is a thread on how to flush the system, it might have a piece of trash in it. And just an FYI bullydog tuning is terrible, if you keep running it you will have to build your tranny.
