84-84 C4 Hypertech Thermo Master Power Chip Automatic

A Hypertech Power Chip offers significant performance improvements. At wide open throttle, the Power Chip selects an optimum spark advance and air/fuel ratio, allowing the engine to perform beyond the limitations of a stock chip. Because the Power Chip only affects the wide-open throttle operation, fuel economy is unaffected. The Hypertech Power Chip is available in two versions: Street Runner is designed for stock or slightly modified Corvettes and will yield the results already mentioned, while Thermo Master has been further modified to allow the use of a cooler (160?) thermostat. A cooler engine produces more power than a hot engine.
