The 12500 Performance Module fits 8.3L ISC & 8.9L ISL engines. 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.

8.9 2008 Cummins ISL Has a DpF filter.

This would be the module specified to work for your model: https://www.ultrarvproducts.com/8210104-TS-Performance-MPHD-Cummins-8.3L-ISC-8.9L-ISL-2008-Current

Although this Area Diesel module says 2009+, I do believe the 2008 models are the same and it should work.
