Fuel Your Ambition With All Out Performance

If your build is already pushing the limits of air and tuning, the Exergy E02-10520 300% Over Injector is the next step to take things even further. These injectors are built for trucks that see competition use and demand extreme fuel volume to support massive power output. Whether you're drag racing, sled pulling, or maxing out a dyno sheet, this level of fuel delivery gives your LML Duramax what it needs to stay in the fight. They’re not meant for daily driving or mild performance, but when paired with the right turbo setup, dual fuelers, and custom tuning, they bring serious horsepower to life. Each injector is precisely flow matched to ensure consistent fueling across every cylinder, helping keep power predictable under load. If you're already deep into your build and ready to squeeze every last bit of performance out of your fuel system, this injector set won’t hold you back. Backed by Exergy’s reputation for quality and race-proven performance, these are purpose-built for results.

Calibrated For Control When Maximum Fuel Is Required

The Exergy E02-10520 300% Over Injector is engineered with extreme performance in mind, using the same OE-grade development approach found in factory fuel systems. These injectors begin as remanufactured OEM units and are then flow modified to deliver triple the fuel of a stock injector. Every unit is tested using Bosch calibration equipment, allowing Exergy to map injection timing, quantity, and shot-to-shot consistency across a wide operating range. The testing process extends from idle to full power, incorporating custom calibration points tailored to high-performance demands. This level of detail ensures that even at peak flow, the injectors maintain stability and predictable fueling. These are best suited for builds utilizing stand-alone engine control or advanced tuning platforms like EFI Live. Proper setup with adequate pump support is essential, as the injectors are designed to support power levels well beyond what most fuel systems can handle on their own. Built for dedicated race builds, these injectors reflect the precision and capability that Exergy is known for.
