Re: 2003 8.1 l 2500
Those things were a problem to get past EPA certification. A friend of mine is a GM Calibration Engineer, and worked on that deal. Power and gas mileage left on the table there. All in the computer.
I have not heard any complaints about durability. I had one in a motorhome. Thought it was fine. Had mine up to 8 mpg towing my race car, if I stayed under 70.
