OnKill Tuning is a family operated speed shop in a suburb of Springfield, MO. We specialize in tuning, which is the process of optimizing a vehicle's fueling, ignition, and other subsystems to meet the customer's needs and maximize the performance of a car. Each engine is different from the moment it leaves the factory, and will see gains from a calibration written specifically for it.
Quality tuning work takes a significant amount of time, as well as experience that most people haven't had the chance to be exposed to. Whether you seek more power, fuel economy, or are building an all out race car, we can use our experience to get your project across the finish line.
