Exhaust brake tune

Is there a tune to improve the exhaust brake on my 2012 6.7 cummins with automatic. Since I installed my mini maxx my exhaust brake does not hold as well as before. I did the full egr and cooler deletes thank you for all your help

  • No, unfortunately what you have is what your going to get. Since H&S Performance is out of business, there are no longer any modifications to tuning.
  • Ok thanks
