The increased flow rate of these Stage 2 Powerstoke Fuel Injectors with 80% nozzles are capable of producing more than 80 RWHP over our Stage 1's, and more than 100hp with the 100% nozzles, These Powerstroke fuel injectors by Unlmited Diesel are great for a person that wants to use their truck for daily driving, towing, or just playing around on the street. You can literally detune these diesel fuel injectors to run stock HP Levels or power levels of more than 425 RWHP.
