Just purchased a 2003 2500 5spd 4whl drive with a 250hp cummins and want to know which boost or performance module is best. (Please no wars) The truck is used for towing occasionally. I hate to modify the engine by injectors because of the good fuel mileage. But after driving a 78 crewcab with my slightly modified 97 cummins and 5spd for several years, I am a little disappointed with the performance of this truck. Don't get me wrong, but the old truck had a lot more zip out of the hole and at 50 mph in fifth. I would like to retain the mileage, reliability and add a little more power. What do you 3rd genners suggest?
