Jeffrey 34 Posted Thursday at 10:33 PM Share Posted Thursday at 10:33 PM I have a 2006 Mack vision with 355/380 egr aset engine ,I’m wanting to swap out for a low mileage 427 egr aset engine ,was wondering if I would have to do any reprogramming of software or would it work just plugging my harness into the 427 ecm ,any help would be appreciated.
