Unlock adjustable power on your 12-valve with the Dynomite Diesel (DDP) FPLATE Adjustable Fuel Plate Kit.

This kit is designed for 1994–1998 Dodge Ram 2500/3500 trucks equipped with the 5.9L 12-valve Cummins and P-7100 injection pump. Unlike fixed-grind fuel plates that lock you into one power level, the DDP adjustable plate lets you dial in gains ranging from approximately 25 to 140 rear-wheel horsepower, depending on your pump setup and supporting modifications. It works well on relatively stock trucks and scales up to high-horsepower competition builds (1,000+ RWHP applications).

Key Features

• Custom Dynomite Diesel ground adjustable fuel plate (not a standard numbered grind)
• Adjustable power range for fine-tuning performance, smoke, and drivability
• Suitable for daily drivers through serious performance builds
• Straightforward installation with no major modifications required

Kit Contents

• Adjustable fuel plate
• Boost elbow
• AFC spring
• New AFC housing fasteners

Important install note: Use the included AFC spring only with injectors capable of supporting more than 525 RWHP. Installing it with stock or smaller injectors can reduce low-RPM performance and throttle response. Reuse the stock AFC spring in those cases.

Fitment: 1994–1998 5.9L 12-valve Cummins (P-7100).

Dial in the power level that fits your truck—whether you want better daily driving response or more fuel for weekend pulls—with the DDP FPLATE adjustable fuel plate kit.
