The Best Money You’ll Spend On Your 5.9 Cummins Truck:

  • FULL 48RE Custom Tuning that others say is impossible (More Info) 04-07 5.9 Cummins Trucks
  • Engine Tuning For 03-07 5.9 Cummins Trucks
  • I use proprietary parameters that are not available in off the shelf tuning programs used by other custom tuners
  • My custom tunes are edited at the code level, not just with standard tuning software used by most tuners
  • Most other custom tuners have to focus on keeping up with the new trucks year after year and rarely go back to develop improvements for earlier model year trucks; 3rd Gen 5.9 Cummins Trucks are what I specialize in.
  • Customer Service: There is NO substitute for good service. I will work with you as long as it takes until you are satisfied.
  • No Middle Man:  You will be communicating directly with the person working on your truck.
  • International Customers Welcome!

I’m sure you have heard or read: 48RE shift points can only be adjusted by replacing the valve body or installing a shift kit…  This is not true.

There are literally thousands of adjustable engine and transmission parameters in the 2003-2007 ECM software and only a handful of those parameters are included in off the shelf tuning programs used by most custom tuners.  My tunes take full advantage of these “hidden” parameters.

I assure you the ECM/TCM is in complete control of the shift points and torque converter lockup in a 48RE Transmission which you will notice immediately when you drive your truck the first time after installing my tunes.  Your truck will drive like it should have from the factory…

I like helping people appreciate their trucks:

Originally I got into tuning by experimenting on my own truck (an 05 Auto). I had a feeling there was a lot more these trucks had to offer than how they came stock: Many years down the road I can say that was an understatement.  There is a whole different truck waiting to be released inside your ECM. Helping customers unleash that new truck is what I enjoy doing.
