Your engine is operated by a hard drive, same as your computer. We refer to your engines hard drive as an ECU. Every ECU requires an operating file or tune. Performance software tuning is the process of installing a new operating file calibrated specifically for your vehicle.

The fact is, if you have a car that came from the dealer equipped with a turbo or supercharger, and its stock, then your car is slower than it needs to be! We have stage 1 tunes designed for otherwise stock vehicles, that offer increased HP when you want it, without sacrificing reliability.
