The Dynomite Diesel DDPNLMM-300 is a set of brand-new fuel injectors engineered for 2008-2010 Chevy and GMC 6.6L Duramax LMM trucks. These injectors are designed to significantly increase fuel delivery, with nozzles flowing at 150 percent over stock and incorporating internal calibration upgrades. This injector set is capable of supporting up to 1175 RWHP when paired with the necessary supporting modifications. Key features include a 150% flow rate increase over stock, adding approximately 300 extra horsepower, and a complete set of 8 balanced and matched brand-new injectors. The SAC Style Nozzle is utilized, and a pyrometer is recommended for monitoring exhaust gas temperatures. Installation of these injectors requires a modified or dual CP3 pump and upgraded turbo(s), along with custom tuning. Due to their performance nature, they are not recommended for daily driven street applications. A core charge applies to this set. Dynomite Diesel backs this product with a 2-year unlimited mileage warranty. It is crucial for the purchaser to confirm the correct injector sizing for their specific application. Research, consultation with a tuner, and direct contact with Dynomite Diesel sales staff are strongly advised before purchasing. Dynomite Diesel is not responsible for damages or issues arising from incorrectly sized injector sets, and returns, refunds, or credits will not be honored once the injectors have been installed.
