Level 1 Tuning - This option is designed for vehicles enhanced with a supercharger, turbocharger, or nitrous system. It's also appropriate for vehicles that originally came equipped with forced induction from the factory, such as a CTS-V2 or C7 Z06. Level 1 tuning is best suited for applications utilizing the stock camshaft, focusing on maximizing performance gains from basic forced induction or nitrous setups. It provides a noticeable improvement in horsepower and torque while maintaining reliability.

Level 2 Tuning - This option builds upon the capabilities of Level 1, expanding compatibility to include vehicles running alternative fuels and those upgraded with aftermarket camshafts. Level 2 tuning level also unlocks Flex Fuel tuning, allowing your vehicle to seamlessly adapt to varying ethanol content in the fuel for optimal performance and efficiency.
