I've had so much go wrong with it that I can't remember when it all happened.

They did update both VECU and EECU...at the moment I can't remember if the turbo was replaced before or after that.

Code 45 came up once after having the EGR replaced...cant find any information as to what that code is. Hasn't been back on since. Fuel and boost pressure is fine.

Purchased the truck in Feb 2015 and have had nothing but trouble since. Complete motor rebuild...all new computer...EGR system...turbo...you name it...it's been replaced. With that being said it still doesn't want to pull. Any suggestions as to what may be the problem???? It is a Mack Vision 350 turned up to a 427. Runs great a few weeks then decides she doesn't want to pull...
