Diesel Tuner's Blog

03-05 Cummins Custom Tuning is Finally HERE!

For over a decade the diesel performance industry has been waiting for REAL custom tuning for their 2003 - 2005 Cummins.  These early common rail engines have dealt with box programmers and pressure boxes for long enough, finally there is a solution.

MM3 Tuning has been out for less than a year and has already made a big splash in the highly modified Cummins world.  With the capability to tune 1998.5 to 2017 Cummins this tuner has a wide range of support.  

However many different reasons there are for the success of this new Smarty based custom tuning platform I dont know, but the 3 reasons below are certainly the most common ones we here at Calibrated Power.

1000HP Daily driven Single turbo 5.9 Cummins

Generally the terms "budget" and "1000RWHP" are opposing descriptions.   This build ties the two together while utilizing the highest quality parts in the industry.   The owner, Mitch, who has owned this truck for some time has always envisioned a 4 digit street truck. 

If you have been around the Cummins performance community for any length of time you understand how amazing it is to make over 1,000HP on a single turbo setup that is still streetable.  Of course many people have made the power, but with a single turbo the big problem is spool-up and smoke output.  With Mitch's truck we dialed in a parts package and our custom tuning so he could have the best of everything with his truck.
