Adjust Cooling Fan On/Off Temperatures!

With the Power Programmer, you can electronically adjust the "on/off" temperatures of your vehicle's electric cooling fans. When used with a Hypertech PowerStat, low-temperature thermostat, this produces a cooler, denser intake charge that allows the engine to make more power. A cooler engine is also less likely to detonate under heavy loads. That means better performance for you and longer life for your engine.

Depending on Model Year, Recalibrate Your Speedometer, Odometer, and Part-Throttle Shifting at the Push of a Button with Hypertech!

If you've installed non-stock tire sizes for more grip on the road, taller tires for more traction on the strip, or a different rear gear ratio, you must reprogram your vehicle computer for correct speedometer and odometer readings, as well as correct part-throttle shifting. That's because the electronic "brains" in late-model vehicles are programmed to work properly only with the factory-installed tire size and rear gear ratio. The Hypertech Power Programmer III lets you reprogram your vehicle's computer for non-stock tire sizes and/or rear gear ratios at the push of a button!

Here's How It Works!

The vehicle computer calculates your vehicle's speed based on the diameter of the stock tires. If you've installed taller or shorter tires, or changed the rear axle ratio, the vehicle computer doesn't know how fast your vehicle is really going. As a result, the automatic transmission may not shift correctly and the speedometer/odometer readings will not be accurate (as required by law). The Hypertech Power Programmer III lets you select different tire sizes and rear gear ratios, then stores that information in your vehicle computer. And that's just the beginning!

Modifying your vehicle has never been easier. Just plug the Power Programmer III into your vehicle's underdash diagnostic port, answer a few simple "yes/no" questions, and the Power Programmer III does the rest. You'll get Hypertech's exclusive Power Tuning that maximizes your vehicle's performance and brings out the best in popular performance modifications like low-restriction air cleaners and/or cat-back exhaust systems. And best of all, you can change your options or restore the stock tuning whenever you want.

Hypertech Dual Fuel Feature Delivers Premium Performance on Regular Gas!

Hypertech is easing the pain of rising prices at the gas pump. Hypertech has developed exclusive "Dual Fuel" tuning calibrations that deliver virtually the same power increases with regular gas as they do with premium. Hypertech's Power Programmer is the only device that offers this powerful Dual Fuel feature.

"The truth is that most trucks make exactly the same power on tuning optimized for regular as they do with optimized premium," explained Mark Heffington, the founder and president of Hypertech. "For these vehicles, there is never a reason to use more expensive premium unleaded."

While some competitors claim to have tuning for regular gas, their calibrations for regular gas typically make no more power than the stock tuning. In contrast, Hypertech's optimized power tuning for regular gas produces virtually the same power gains as the premium gasoline tuning. For example, Hypertech Power Tuning for a 2003 Hummer H2 with a 6.0-liter V-8 engine adds 17 horsepower over stock with regular gas and 22 horsepower with premium.

Owners of trucks and SUVs are concerned with the cost of operating their vehicles. That's why Hypertech engineers use computer-controlled chassis dynamometers to develop fuel curves and ignition timing calibrations to maximize performance and fuel economy with regular fuel.

"Hypertech Power Tuning for regular grade fuel is substantially more powerful than stock tuning with either regular or premium fuel," Heffington noted. "Simply stated, this means increased power for less money. It's a win-win situation because truck and SUV drivers get more power for towing and save an average of 25 cents per gallon at the pump."

Hypertech builds, tests, certifies and sells on-highway power-enhancing products that are safe, legal and optimized for the best possible performance. Unlike reprogramming devices that are sold for "off-highway" use only, Hypertech's Power Programmer is street legal in all 50 states, with certification received or pending from the California Air Resources Board (CARB). This assures owners of Hypertech products that they will meet certification requirements when undergoing emissions tests administered by state or local agencies.
