1990 Hypertech Thermomaster Power Chip (350TPI Automatic)

1990 Camaro/Firebird/Trans Am 350 TPI; Auto w/OD Hypertech Thermomaster Power Chip

The ThermoMaster Power Chip, used in conjunction with a low-temperature PowerStat thermostat, is the most powerful chip you can run on the street. The ThermoMaster 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. Cool air has more air molecules per cubic inch than hot air. An engine running in cool, dense air produces more horsepower and is less likely to detonate than an engine that is taking in hot air.

The Hypertech PowerStat thermostat lowers both the temperature of the incoming air/fuel mixture and the engine coolant temperature. The ThermoMaster Power Chip is programmed to take advantage of this cooler, more powerful air/fuel mixture produced by the Powerstat. All temperature-sensitive functions controlled by the ThermoMaster chip (such as a 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. The Hypertech PowerStat is specifically designed for use with the Thermomaster Power Chip.
