DDP LBZ-75 Remanufactured Injector Set — 30% Over / 75 HP

Give your 2006–2007 6.6L Duramax LBZ the extra fuel it needs to wake up. The DDP LBZ-75 remanufactured injector set flows 30% over stock and is built to deliver about 75 horsepower at the wheels. It is the largest injector size Dynomite Diesel recommends for a stock CP3 and stock turbo, with the ability to support 675–700 RWHP once the rest of the truck is properly supported and tuned.

These are not generic remans. Each set is remanufactured, flow-tested, and sold as a balanced, matched eight-injector package so cylinder-to-cylinder fueling stays even. That means cleaner power delivery, better drivability, and more consistent performance than a mix of unmatched injectors.

The nozzles use DDP’s SAC design with patented two-pilot-hole technology (7-hole plus two 0.005" pilots). The result is improved atomization and a stronger, more controlled spray pattern — more usable power without simply dumping extra fuel.

Who this set is for This is the sweet-spot upgrade for an LBZ that still runs a stock high-pressure pump and turbo. It adds real power for daily driving, light-to-moderate towing, and performance use. It is not the right choice for frequent or heavy towing on a stock turbo.
