HOW MUCH POWER FROM A STOCK TRUCK?
How much horsepower can my truck make with a programmer? It’s a question we get a lot. And—as you can imagine—it isn’t the easiest one to answer. Truth be told, the real question is: How much power can I squeeze out of my stock injectors, turbo and transmission? Being that more than 80 percent of all diesel owners call it quits after installing a cold-air intake, exhaust system and tuning, this is an area that definitely appeals to the masses. Compiled from our years covering dyno events, attending private dyno sessions and testing parts on our own project vehicles, we’ve broken down the maximum rear-wheel horsepower each brand is capable of producing when a tuner is used as the sole power-adder.
And because we’re often asked who makes the best tuning for a specific make and model, be it Ford, Ram or GM (Power Stroke, Cummins or Duramax), we’ve included the type of device and software we tested that allow the numbers listed here to be achieved. As you peruse our comprehensive list, keep in mind that every truck is different. Some simply run better than others. For example, we’ve seen a 20hp difference between two (presumably healthy) LBZ Duramax engines running the same EFI Live tune, on the same dyno, and on the same day. For this very reason, a 20-30hp variance is built into each section below. We’ll kick things off with the ’94.5-17 Power Strokes, then shift to the ’98.5-17 Cummins, and conclude with the ’01-18 Duramax-powered GMS.
