The 52000 Performance Module fits Cummins 5.9L ISB, 6.7L ISB, 8.3L ISC and 8.9L ISL engines with common rail fuel system. This module does not flash or connect directly to your ECM. It plugs into the engine harness and intercepts signals going back and forth between the fuel injectors and the ECM. It uses factory spec connectors and does not require any splicing or modifications to your engine harness.This diesel performance module is designed for optimizing the fuel delivery system to extract more power from your engine with up to 30% increase in horsepower and torque and 10-20% increase in fuel economy. Adjustable with a four position switch, Stock, +10%, +20%, & +30% power. 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 while delivering 10-20% better fuel economy. How is this possible you ask? The programming in the module is self-adjusting based on load and will deliver more power when needed but better fuel economy when not needing it.

The module receives the data from the ECM and optimizes 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.


I have a 2008 Holiday Rambler MH, it has a 2005 Cummins ISB325 motor with EGR. Will this work on it. ( Brad McLean, 09/11/2023 )
This should be correct but if you could supply your Cummins engine serial number, we can verify. ( Support )
