For 25 years, Ford has been bolting direct-injection, turbocharged V-8s between the frame rails of its trucks and adding Power Stroke badges to its sheet metal. For the majority of those years, diesel enthusiasts have been searching for, and actively finding, ways to extract more power from these highly capable engines.

From the early days of physically adding a chip to the 7.3L Power Stroke to the current ease of tuning your 6.7L’s PCM with your smartphone, the goal has remained the same: Add power affordably—but also reliably. After all, while all of us want more power and endless capability, none of us wants to sacrifice a transmission, head gasket or piston in the process.

To keep your engine in one piece throughout your pursuit of power, you’ll find the following parts “recipes” extremely helpful.

Ready to triple the horsepower of your lazy, stock 7.3L without having to retire it from daily driving duties? How about making sure your 6.0L runs with newer trucks by doubling its power output? Own a 6.4L Power Stroke?

We’ll show you the most durable and affordable path toward owning a 750 rwhp workhorse. Or, maybe you’ve moved into a 6.7L Power Stroke and are ready to unleash the potential of the factory injectors with a dual highpressure pump kit and a turbo upgrade?

From mild to wild and budgets ranging from $1,000 to 20-large, it’s all here.

7.3L POWER STROKE (‘94.5–’03)

The first thing to point out with the 7.3L Power Stroke is that stock injector ‘94.5–’97 engines are more limited in their performance potential than ‘99–’03 versions. This is due to their single-shot, AA code injectors flowing 95cc versus the split-shot, AB codes used on early-’99 mills (as well as ‘97 CA models) flowing 120cc. Larger, 130cc to 140cc splitshot, AD code injectors came standard on ‘99.5–’03 7.3Ls, hence their ability (along with a 17-degree, high-pressure oil pump and electric lift pump) to make the most power of any stock injector 7.3L. However, once you get into bigger injectors and other supporting mods (which our larger-power budgets do), all 7.3Ls have the same power potential.
