Fits 2003-2004 Cummins 5.9 I would like to get $150 for it

I used this in my early 04 Dodge Cummins. Noticeable power gains and I also picked up 1-1.5 mpg with it. No longer need it. I am open to offers on it. Below explains what it does.

The Power Edge EZ is a plug in module that maximizes engine efficiency by monitoring the RPM, timing, turbo boost pressure and fueling parameters to determine both fueling and timing enhancements for the Bosch fuel injection pump.
The re-mapping of the fueling and timing parameters is done via the CAN-BUS communication system. The CAN-BUS protocol is used to communicate between the Cummins Engine Control Module (ECM) and the Bosch fuel injection pump. All data sent from the Power Edge EZ is within the limits of the Bosch fuel injection pump. This enables smooth and predictable power delivery without compromising integrity. This increase in power does not increase the exhaust smoke from a stock engine.

The Power Edge EZ allows maximum fueling at full turbo boost and provides an additional 65 rear wheel hp, an additional 185 ft-lbs of torque and installs in minutes. Simply plug the Power Edge EZ connectors into the ECM Data Link connection and MAP sensor.
