The 175/146 injectors are a terrific upgrade for those 1999-2003, 7.3L owners looking for efficiency, as well as a modest power increase. The 175 single shot injectors retain the OEM ("146"nozzle), use NO more high pressure oil than stock AD split shot injectors, yet flow 25+cc's more fuel. "Off the shelf" programmers, and "generic" chips will not work with this style injector, as injection timing and fuel feed rates have to be adjusted to accommodate the single injection event. Reprogramming of TS performance chips, as well as Bullydog chips are offered at no charge at the time of injector purchase.
The 175/146 single shot injectors have shown to consistently make over 375 rear wheel horsepower, which is a 60hp+ gain, over an already "hot-chipped" Super Duty truck. With our custom tuning, we have been consistently increasing fuel economy 2-3mpg with these injectors! *1200 core charge on set of eight These Injectors will require custom tuning to work properly! | Available Options: | | Choose Here: | | |
