In the last quarter century, tuning a car has become far easier than it was in generations past. Computers began governing the inner workings of cars a few decades ago, and tuning became less about wrenching under the hood and more about computer programming. Hypertech has built its business on this fact. Most cars manufactured in the last decade or so have writable electronic control units, but older models' electronic control units are controlled with chips. Hypertech Performance Chips are designed to serve as upgrades over the preexisting chips in such older vehicles. These chips will adjust the ignition timing and the air-to-fuel ratio in your vehicle to give it a boost of power and a noticeable increase in performance. Hypertech Performance Chips are easy to install and can be done in minutes. To install this chip, simply locate the electronic control unit and the chip on it, remove that chip and install the new Hypertech Performance Chip. The installation process usually requires no more than a few minutes and a screwdriver. And as a return on the little time and effort you have invested in installing this chip, you will see immediate gains in power and performance.
