Stage 1 Package - 350HP | OBS 94-97 7.3L Powerstroke
On OBS trucks, Stage 1 (AC Code) injectors are a fantastic stock replacement and for trucks intended to tow frequently. Without any tuning in the truck they will run exactly like factory injectors and do not require any additional modifications. If you want to use them to their full potential you will need additional supporting modifications though. This package is a great way to combine parts that work well together.
Choosing the Right Parts:
- Injector Options:
Full Force injector warranty - 18 Month Unlimited Mileage Warranty!
Unlimited injector warranty - Lifetime Unlimited Mileage Warranty!
- Tuning Options:
PHP Hydra + 1023 Diesel Tuning - Choose this if you do not already own a PHP Hydra.

KC Balanced Assembly: If you are willing to rebuild your own turbo and don't intend to tow heavy in higher power tunes. (more info)

Q. Will I need an Upgraded HPOP (High Pressure Oil Pump)?
A. Most likely yes, especially on OBS and Early 1999 7.3s. These trucks had lower performing 15* HPOP’s from the factory. You should be able to maintain over 2,800PSI of Injection Control Pressure at Wide Open Throttle, if your truck can not do this you need to upgrade your HPOP.
Q: What Transmission Upgrades Will be needed?
A: If this is a daily driver/tow rig that is not beat on constantly, a healthy stock transmission will generally last very well. It is our recommendation that unless your transmission is low mileage and very healthy that you leave it alone and only purchase a well built transmission when its needed rather than attempting to modify the stock transmission to handle more power.
Q: My Truck has a manual transmission, do I need a better clutch?
A: If you are going to use near the max potential of these injectors (and support modifications) you will need to replace your factory clutch with something better. Check out our clutch selection!
Q: Do I need to upgrade the fuel system with stage 1 injectors?
A: Switching to an electric fuel system will be necessary to make the most of these injectors. But it is not required if you are just using these as a stock replacement.
It is recommended that you maintain no less than 50 PSI of fuel pressure or you can damage the injectors. For Ideal performance you should be maintaining between 60 and 70 PSI of fuel pressure.
What Can This Kit Be Used For?
This package is great for towing any weight and fast spool up, while staying reliable and not needing head studs, valve-springs, and pushrods.
A stock OBS truck will dyno at around 150HP and 325lb.ft of torque.
This setup is capable of 300-350HP and 650-700lb.ft of torque.

I decided to go with this package as I was looking for a little more power for my old Beast and to replace the old 230k clapped out injectors and boy did it deliver! I got the 160 unlimited injectors, added an intercooler setup, an .84 turbine housing and a billet wheel and it’s a completely different truck. Be careful though, your fuel mileage is gonna take a dip because of your right foot…
