DDP LBZ-ECO Economy Series Remanufactured Injector Set – 2006–2007 6.6L Duramax

Restore clean, confident power to your LBZ—without the cost of a high-output build.

The DDP LBZ-ECO Economy Series remanufactured injector set is built for 2006–2007 6.6L Duramax owners who want a better-than-stock replacement: smoother running, sharper throttle response, and a modest 10–20 RWHP gain, all while keeping excellent fuel economy and everyday drivability.

Aging LBZ injectors often show up as lazy response, uneven idle, extra smoke, and falling MPG. This complete remanufactured set replaces all eight injectors as a matched, precision-balanced package. Each injector is remanufactured to tighter flow tolerances than typical OEM units, so the engine gets consistent fuel delivery cylinder to cylinder. The result is cleaner combustion, little to no smoke, and a truck that feels tighter and more responsive under load.

This is the mildest performance step in the Dynomite Diesel lineup—purpose-built for stock trucks. No aggressive nozzle sizing, no requirement for supporting mods, and no sacrifice in daily manners.

Why this set
