MM3Tuning.com is the #1 engine and 48RE transmission tuning solution specializing in 3rd Gen 5.9 Cummins Ram trucks. Almost all other tuning solutions are working on keeping up with the new trucks year after year which leaves little time for them to work on 3rd Gen 5.9 Cummins trucks.

-The Smarty MM3 tuner coupled with UDC Pro Tuning.
