Product Description
EDGE PRODUCTS 30305 COMP BOX FOR 1998.5–2000 DODGE RAM 2500/3500 5.9L CUMMINS DIESEL
The EDGE PRODUCTS 30305 COMP BOX is one of the most legendary power modules ever produced for the 1998.5–2000 5.9L Cummins, delivering massive gains in horsepower, torque, throttle response, and fueling control for VP44-equipped trucks. Designed to dramatically improve both street performance and towing capability, the Comp Box provides one of the strongest increases in low-end torque available for early 24-valve trucks.
The Comp Box intercepts fuel signals and optimizes delivery timing, duration, and pressure to unlock the full potential of the VP44 pump. Adjustable power levels allow you to choose settings for daily driving, towing, or maximum performance. When paired with appropriate airflow upgrades, the Comp Box supports extremely strong power growth—all while maintaining smooth drivability.
Installation is straightforward with Edge’s harness system designed for VP44 applications. The module mounts cleanly under the hood and plugs directly into factory connectors with no ECM flashing required.

FAQ
How much power can the EDGE 30305 Comp Box add?
Depending on truck setup, airflow mods, and power level selection, the Comp Box is known for delivering some of the strongest power gains available for the VP44 Cummins platform.

No. It is a signal interceptor module that adjusts fueling and timing externally—no flashing required.
Do I need to upgrade my clutch or transmission?
If using higher power levels, especially on manual transmission trucks, an upgraded clutch is strongly recommended to handle added torque.
Is the Comp Box safe for towing?
Yes, when used on moderate power settings and with EGT monitoring to ensure safe temperatures.
Can this be used on 12-valve or common-rail Cummins engines?
No. The 30305 is exclusively for VP44-equipped 24-valve Cummins engines (1998.5–2000).
