400CC performance injectors can increase horsepower up to 700 hp+ at rear wheels with a custom performance chip. These are straight up competition injectors. You won't be on the street with them. In the 99-03 Powerstroke diesel you will have to run a custom programmed chip to make the transition from split shot injection to the new single shot injection. Horsepower increases up to 700 hp and mileage increase from the more efficient single shot design. These injectors have new nozzles and tungsten coated plungers and barrels. The larger 400% oversize nozzles allow for better control of fuel delivery during the combustion cycle with allows for the added horsepower over the stage one injectors. The larger hybrid plunger and barrel in these injectors move more fuel for the same stroke as the stage two injector. These hybrid injectors are designed to operate with stock High Pressure oil. This is stretching the limits for the 17 degree HPOP. This saves money on a new HPOP system by utilizing the system you already have. Built and flowed to within 1%.
