These engines are now going out of warranty (mine is out) and I see some posts about aftermarket tunes for more torque at lower RPM.
Where are these available?
The original early cummins tune was upgraded by the factory through an early "send in your ECU" program... do the new tunes include all of this or would an early engine be best contacting cummins for the base upgrade and then doing the aftermarket tune up?
