Performance Chips »
The Hypertech Thermomaster Power Chip is designed for use with a low-temperature thermostat, such as the Hypertech PowerStat. The Thermo-Master Power Chip used with a PowerStat is the most powerful chip you can run on the
street. Cooler air, with more air molecules per cubic inch, will deliver more horsepower and reduce the tendency to detonate. It not only provides maximum performance, but it will also help keep the engine cooler in
situations of extreme heat such as emergency vehicles, desert driving, competition, etc. All temperature sensitive functions controlled by the chip (such as minimum temperature for torque-converter lock-up, closed loop
operation, and in some cars, early fan turn on) are adjusted for a cooler temperature thermostat. Please call for California-specific vehicle applications. (*After part number indicates that a Hypertech Cool-Fan Switch is
recommended for that application.)
