Please note when purchasing a handset as a dispatch order to tune from your doorstep, we aim to tune the vehicles as precisely as possible based on the average mileage vehicle. As the vehicles age, hardware can become weaker, resulting in boost leaks, weak diverter valves, lazy actuators and so on. With this being said to tune your vehicle with complete accuracy, data logs are required. Please contact your local TRS dealer for this service.
