DDP Dynomite Diesel Injectors — Duramax, Cummins & PS

DDP (Dynomite Diesel Products) manufactures performance diesel injectors and fuel system components engineered for Duramax, Cummins, and Power Stroke platforms. DDP injectors are precision-calibrated and flow-matched in-house, delivering cleaner combustion and consistent power across all cylinders compared to OEM injectors that wear unevenly over time.

Popular Upgrades

DDP stage 1 and stage 2 performance injectors for the GM 6.6L Duramax LB7, LLY, LBZ, LMM, LML, and L5P are the most popular products in the DDP catalog. Cummins 5.9L and 6.7L injector upgrades from DDP are popular in builds targeting 500 to 800 horsepower from the ISB platform. Power Stroke 6.0L and 6.7L performance injectors complete DDP's coverage of the three major domestic diesel engine families with flow-matched sets ready for professional installation.

What does a DDP stage 2 injector upgrade do?

DDP stage 2 injectors increase fuel delivery capacity beyond the stage 1 specification, allowing the engine to support higher horsepower targets when paired with a supporting tune and upgraded fuel supply components. Stage 2 injectors are calibrated to tighter tolerances than OEM units and flow-matched as a set, which improves power delivery consistency across all cylinders. A professional EFI tune is required after any injector upgrade to calibrate fueling maps for the new injector flow rate.

Do DDP injectors require supporting modifications?

Performance injector upgrades produce best results when paired with an upgraded lift pump or FASS fuel system to ensure adequate fuel supply pressure, an injector return line upgrade to manage fuel return temperatures, and a custom EFI tune to optimize injector pulse width and timing. High-output builds beyond 600 horsepower may also require a CP3 pump upgrade or compound turbo system to support the increased fueling and airflow demands.
