The Cummins motor is one of the most powerful motors ever put in a pickup truck. The Edge EZ module unleashes the potential of this monster by carefully monitoring RPM, turbo boost pressure and fueling parameters and adjusting fueling to maximize power, torque and driveability.
The Edge EZ module allows maximum fueling at full turbo boost and provides an additional 70 rear wheel horsepower and an additional 220 foot pounds of torque. Simply plug the Power Edge EZ connectors into the ECM Data Link connection and MAP sensor. The Edge EZ is completely weatherproof and mounts under the hood. The Edge EZ module can also be set to zero for heavy towing without having to unplug the module.
All data sent from the Edge EZ module is within the limits of the Bosch fuel injection pump. This enables smooth and predictable power delivery without compromising integrity.
The EZ can also be stacked with other upgrades to deliver even more power. There is not an upgrade on the market today that can deliver as much power and install so simply.
Legal in California only for racing vehicles which may never be used upon a highway.
 | The included brass elbow permits turbo boost pressures of greater than 20 psi without the wastegate opening. The EZ module will operate equally well with or without this installed. |

exactly what I needed!!This product is exactly what I needed towing my 5th wheel. I leave it on the lowest setting and have plenty of power with decent mileage. Just took a trip without trailer, drove 70-75 mph and got 21-22 mpg. 2003 4x4 w/ manual transmission. I highly recommend this product.

Just installed yesterday, Seems like product does what is says. The package says installs in 5 minutes, But reality the first time is a little longer like at least a hour or so. Called edge tech support a couple of times with questions. They were helpful.

- How to Switch Between Power Levels With Edge EZ on Dodge RamI reached out to my contact at Edge and they let me know that the Edge EZ for Dodge Cummins 5.9L # EP30203 does come with a switch so you can make your adjustments inside the cab of your truck without having to go to the box. A replacement switch is available as well with # EPHESW3-2. Since the tuner does not have a display I recommend the Edge Insight CTS3 Comprehensive Gauge Display # EP54FR.

If you check the VIN of your truck the eighth digit will be the letter C if your truck has the H.O. Cummins. Also it will say 305 on the ID tag of the truck.

view full answer... - Can or Should a Gauge Display be Used with the Edge EZ ProgrammerIt is a good idea to monitor the engine performance when using a programmer such as the Edge EZ # EP30203.

It will not fit the 2001 models. You would need the specific tune of Edge EZ programmer # EZD1000A for a 2001. Each programmer is designed for specific trucks and cannot be used on models they were not designed for.
