When it comes to power tuning, Hypertech is a leader; in fact they invented it. Hypertech optimizes the 3 basic elements of ignition: Air, Fuel and Spark, to produce maximum performance. Hypertech Power Tuning maximizes engine performance by burning the air/fuel mixture as efficiently as possible, thereby extracting maximum power. Power Tuning replaces the stock calibrations in the onboard computers. These complex programs control important engine functions such as spark timing and fuel delivery. For complete control we recommend the Hyperpac a portable Dyno-tester that fits right in your vehicle cockpit. You have full control over everything from increasing horsepower to clearing stingy “check engine" lights. Hypertech also has a number of chip programmers that don’t require you to crawl under the hood to do something as simple as increasing horsepower. The Hypertech Power Programmer III will instantly recognize your vehicle by reading the vehicle identification number and properly optimizing it. If you want to take full advantage of all those parts under your hood check out one of our Hypertech performance products.
