  1. I can ask if the wrong info was entered it should of come up at one dealer or the other
  2. In December 2016 the trk a 2013 CHU with 505 18 spd fuller was at a service dealer for codes which I cant remember Come to find out the airdryer was changed on the road because of failure of the original A regular ad-9 was installed instead of the more advanced ad-9 Anyway while it was at the dealer they run a software or a program upgrade on the trk After that the driver noticed a loss of power So after listen to complaits I sent back to the dealer and they said it needed a new set of injectors at the time the trk had 163,000 miles That was $6000 Still not back to normal Brought it to a different dealer and they put a turbo on it $5500 that seem to bring it back but not fully It was showing 35 to 37 lb boost it should be 40 Complaints are starting again So I decided to ask about what was done in the computer upgrade or reprogramming I have sort of hit a brickwall with that question.I was told to have it dyno checked so I might do that and go from there
  3. Any body else spent 12 grand trying to recover horsepower stolen from a secret Mack computer software change?
