Hey guys, just picked up a low mileage 2003 Cummins 2wd truck, bone stock, thinking of adding a programmer to increase mileage some, haven't towed with it yet, but I do have a 24ft enclosed car trailer I would haul to the track etc.
What is everybody using?, I'm in California, so can't nor do I want to roll coal, race it, its a daily driver, just looking for a bit more mileage.
Thanks in advance,
