HT1010 / 1010 - Application Notes To complete your performance package, Hypertech recommends the use of a low-temp thermostat to compliment the performance tuning found in the Hypertech Power Tuning products. A PowerStat low-temp thermostat improves performance in two ways: first by inducing less heat into the intake air and second by reducing the engine's tendency to detonate.
