Upgrading the injectors in your Powerstroke will deliver a noticeable increase in power, drivability, and even fuel economy. This injector set from the professionals at Full Force start out as new Alliant injectors (not remanufactured) and then the internal modifications are completed to provide the additional fueling for improved power.
Full Force's Stage 2 Performance Injectors have the same internal modifications as the stage 1 and stage 1.5's. The main modification for both injectors is inside the injector on the intensifier piston. This piston is a mechanical limiter, it's modified or shortened which allows the plunger stroke to move slightly farther, allowing more fuel to be pushed through the nozzle during each injection cycle. Each injector is also converted over from split shot to the more efficient and powerful single shot design. The split shot system includes a wasted pilot injection originally designed to make the engine quieter during idle. Converting from the stock split shot injection to a single shot will require custom tuning. Please contact us if you have any questions.
Here's what makes the stage 2 a higher horsepower injector over the stage 1 and 1.5: the nozzle size is larger. These injectors have a nozzle size of your choosing from 80 percent larger than stock to 100 percent larger than stock. The larger nozzle moves the total available fuel (180cc) quicker into the cylinder for a larger, more powerful explosion. The quicker the fuel empties from the injector into the cylinder, the larger, more precise the explosion and more power is achieved. So understanding this, you can choose the larger more powerful 100 or the smaller 80 percent nozzle to reduce smoke and EGT's (Exhaust Gas Temperature) levels slightly.
ADVANTAGES OF THE STAGE 2:
The stage 2 makes more power, but keeps the total CC volume lower over their hybrid cousins. You can make performance oriented power with the same stage 1 total flow rate of 180cc. More power with decent fuel economy is a win-win right? Sort of...
With the larger nozzle comes more smoke. Although you empty the injector quickly, you also provide the truck with a little too much fuel to burn completely in a stock truck. The byproduct is excess black smoke and higher exhaust gas temperature from that wasted fuel. The majority of this smoke comes on the low end of the throttle when the turbo hasn't built enough pressure to utilize the fuel. Most refer to this condition as lugging the engine. This isn't harmful to the engine or turbo but that's when you get the cloud of smoke when you're taking off.
The good news: more of that fuel can be burned or cleaned up with a few more upgrades like an air intake, larger turbo, and/or bigger intercooler.
180cc vs 160cc:
180cc is the best choice for most 1999-2003 trucks. The only time Full Force recommends the 160cc injectors is in high altitude locations or for the customer that doesn't want a large power increase. The only benefit of the 160cc is for converting to a more efficient single shot injector with a very small bump in power.
INJECTOR WARRANTY POLICY:
The warranty does not cover injectors that fail due to bad fuel or trash in the oil system. This also applies to the replacement of scored plungers and barrel assemblies due to bad fuel or the labor to break injectors down to clean poppet valves from dirty oil.
The buyer is to understand that these are aftermarket, high performance items, and Diesel Power Products is not responsible for any damage caused to the injectors or engine due to high EGTs, overrevving, engine failure or any other abuse or neglect.
If there is an injector problem, the buyer will have to purchase a new injector and send in the faulty injector. The buyer will receive a refund on the new injector after the faulty injector is inspected and determined to be covered by the above warranty.

IMPORTANT NOTES:
- Casserly injectors are a single shot injector. 1999-2003 7.3L Powerstrokes run a split shot injector from the factory. In order to switch from a split shot to a single shot injector, custom tuning software is critical for proper engine/fueling calibration.
