LMM Duramax New 75HP Injector Set (30% Over) – DDP NLMM-75

Upgrade your 2007.5–2010 LMM Duramax with the Dynomite Diesel (DDP) NLMM-75 brand-new injector set. These precision-balanced injectors flow 30% more than stock, delivering approximately 75 HP at the rear wheels and supporting 675–700 RWHP when paired with proper supporting modifications and tuning.

This is the largest injector size recommended for use with a stock CP3 pump or turbocharger, making it an excellent choice for street performance and moderate power gains without requiring major fuel system or turbo upgrades.
