Notes

• IMPORTANT NOTE: All nozzles should be installed, and the injectors calibrated, by a professional shop familiar with calibrating oversized injectors. Due to the wide variations in injector calibrations from other manufacturers, we cannot guarantee you will see the stated horsepower gains unless the nozzles are installed by Dynomite Diesel and all other supporting modifications are in place.
• Note: The fuel injector lines on the LB7 are notorious for rusting and causing injector issues. For this reason, we highly recommend replacing your injector lines while changing injectors or nozzles if the lines have not been changed within the last 40,000-50,000 miles.
• Pyrometer highly recommended
• Custom tuning required for best performance
