Hypertech's performance chips and modules modify the ignition timing and fuel delivery to increase performance across the entire power band. Spark timing and fuel delivery are optimized for your specific application.
Available as chips or modules, depending on your application.
Hypertech Cool Fan Switches are designed to be used with performance thermostats for increased horsepower. In some vehicles, the electric cooling fans are controlled by the computer chip, but in others, the cooling fans are controlled by the fan switch (which is usually set to turn on at about 220�F). TPI-equipped Chevrolet engines that have two fans use a fan switch for the second fan, and the first fan is controlled by the computer.
