EGR engine max out at 12 degrees correct? At 14 I am imagining it would have one hell of a vibrate function.

your statements here are heavily flawed.
and no, the engine does not typically "vibrate" etc. with bad injection timing.. that is why so many truck owners swear that the engine seems to typically run ok on horrible, engine destroying programming.

I got this programming corrected and this truck is getting the best MPG in the fleet this past month. 1.1 MPG improvement and I am looking forward to seeing repair costs decline. Thanks guys!
