150 PSI 10 Bar Map Sensor Custom Tuning (Select on checkout)

If you have pushed beyond what the stock 5.9 Cummins MAP Sensor can read, then you are in the right place.  You are probably already aware, these sensors require custom tuning.  If you simply install one of these aftermarket MAP sensors your truck won’t run correctly until the tune in the ECM is updated to reflect the range of the new sensor.

5-9 Diesel can provide custom tunes based on your 100 or 150 PSI 10 Bar Map sensor for your 2003, 2004, 2004.5, 2005, 2005.5, 2006, or 2007 5.9 Cummins Truck or Swap Project. 

Dual CP3 Fuel Pump Tuning

If you are running dual CP3 pumps and don’t want the clutter or cost of an aftermarket control box, 5-9 Diesel can provide custom tunes that will allow your existing ECM to control both pumps directly.  You will only need a CP3 harness splitter (Such as a Fleece CP3X2) to make this work.

Oversize Injector Tuning (Select on Checkout)

This is one of the most common additions to 5.9 Cummins trucks.  Have a set of larger than stock injectors?  5-9 Diesel has you covered!

5.9 Cummins Swaps (Select on checkout)

Swapping a 1998.5-2007 5.9 Cummins engine into your project?  5-9 Diesel is here for you to help with custom tunes and DTC issues.

6.7 Cummins Swap into 5.9 Trucks

We can set you up to use your existing ECM to run a 6.7 Cummins in your 5.9 truck: this swap requires specific custom tuning in most cases to correct for different tuning parameters used between 6.7 engines and early/late model 5.9 Cummins Engines.  5-9 Diesel has your 6.7 swap covered.

Auto to Manual Swaps (Select on checkout)

No problem!  5-9 Diesel can get your ECM programmed PROPERLY as if the truck came from the factory as a Manual. This is a key part of your swap and will eliminate several codes and limiters associated with the automatic transmission that is no longer present.
