Description

Note: Now called a “True” 12 valve tune; here’s why:  All of the major tuning platforms are capable of creating a single injection event tune (12 Valve Tune) by disabling the Pre-injection shot of fuel.  However, there are still common circumstances where pre-injection will return that are NOT able to be turned off via the major tuning platforms; UDC-Pro included.  I have located these parameters and disabled them, so you will never get a pre-injection shot with my 12 valve tunes.  You can only get that here…

12 Valve Tune (Stock HP):

This tune alters your fuel injection programming to run on one large shot of fuel instead of two or three shots of fuel per combustion cycle.  The result is less wear on your injectors and and very different sound which is closer to a 2nd gen 5.9 cummins.  This tune has a small power increase over stock and also has enhanced 48RE shifting patterns.
