Part # 12000 - AG Diesel RV Power Module ISB / ISC / ISL Common Rail


  • 2004-2007 Cummins ISB 5.9L Common Rail

The 12000 Performance Module fits Cummins 5.9L ISB, 6.7L ISB, 8.3L ISC and 8.9L ISL engines with common rail fuel system. This diesel performance module is designed for fuel economy with up to 30% increase in hp and fuel savings up to 10%-20%. Adjustable with a four position switch, Stock, +10%, +20%, & +30% hp. The module doesn't flash the ECM, instead it receives the data from the ECM, optimizes the signal to the engine improving the fuel efficiency and power. Best of all, this module comes with a Lifetime Warranty.
The RV Edition module will increase your power up to 30% over stock and is self-adjusting based on load and will deliver more power when needed.
And before you ask…no this does not flash your ECM! Instead we receive the data from the ECM and optimize the signal to the engine to improve both power and fuel efficiency. True Plug-and-Play connectivity means we aren’t going to ask you to cut and splice any wires. Just connect the module into your existing factory connectors.


Is this the right module,
I am unsure if my rv is a common rail.
I have the allison 3000 transmission and the engine is rated at 400HP


( Steve, 08/12/2020 )
This should be the correct part for a 2006 model. Can you send your VIN or Cummins engine serial # so we can 100% confirm? ( Support )
Isn’t my Cummins engine limited to 340 HP due the Allison 2500 MH Transmission? Engine SN is 73097191. ( Barry Tripp, 04/20/2020 )
Yes you are already at the upper limits of the Allison 2500MH transmission so I wouldn't recommend a module that does not take that into account. The PDI Big Boss Performance Tuner will safely add power because it will read what transmission/engine combination you have and only add a safe amount of power: https://www.ultrarvproducts.com/734001-PDI-Big-Boss-Performance-Tuner ( Support )
