Thumbnail Filmstrip of LLY Duramax New 75HP Injector Set (30% Over) DDP NLLY-75 Images
Dynomite Diesel (DDP) NLLY-75 brand-new 75HP (30% over) injector set
These completely new injectors deliver a strong, noticeable power increase while remaining the largest size recommended for a stock CP3 and stock turbo. Flow is increased approximately 30% over stock, supporting roughly 75 horsepower more than factory injectors and capable of supporting up to about 675 rear-wheel horsepower when paired with the proper supporting modifications.
Each set is precision flow-matched and balanced so every cylinder receives equal fuel delivery for smooth operation and reliable performance. Built from new Bosch-based components, these injectors require no core return or core charge.
Key Features
- Brand-new injectors (not remanufactured) — no core charge
- 30% over stock flow for ~75 HP gain
- Supports up to ~675 RWHP with supporting mods
- Largest injector size recommended for stock CP3 and stock turbo
- Balanced and matched set for even cylinder fueling
- SAC nozzles with patented pilot-hole technology (2 pilots at 0.005")
- 7-hole nozzle design with dual pilot holes
Fitment
- 2004.5–2005 Chevrolet Silverado 2500HD / 3500HD with 6.6L Duramax LLY
- 2004.5–2005 GMC Sierra 2500HD / 3500HD with 6.6L Duramax LLY
Important Notes
- Not recommended for frequent or heavy towing applications when running a stock turbo.

Ideal for daily-driven or mildly modified LLY trucks looking for a clean power upgrade without immediately requiring a larger CP3 or turbo.
