81-81 C4 Hypertech Street Runner Power Chip Automatic

A Hypertech Power Chip offers performance increases and an easy installation.

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 the stock chip. And because the Power Chip only affects the wide open throttle operation, overall fuel economy is unaffected.

The Hypertech Power Chip is available in two (2) versions: Street Runner is designed for stock or slightly modified Corvettes with a stock thermostat. Thermo Master has been further modified to allow the use of a cooler (160-180 degree) thermostat. Lower engine temperatures result in faster acceleration.
