If you were to print all the code programmed into your car’s ECU, it would total over 1,600 pages. In 1985, Mark Heffington founded Hypertech, and for the last thirty years, Mark and his company have continued finding ways to better tune today’s highly computerized automobiles. Their chips and programs take this code and modify for the best performance, efficiency, or both. Their systems can even manage a car’s A/C system. At Hypertech, the emphasis is on having the best personnel for the mission. The members of the Hypertech team are experts and enthusiasts. If you’re looking for a tuning package for your C4 or newer Corvette, one of Zip’s solutions from Hypertech might be perfect for you!
