DYNO TUNING
Dyno tuning allows us to measure real performance gains in a controlled environment. Vehicles are tested before and after tuning to ensure accuracy, safety, and reliability.
ECU REMAPPING
ECU remapping optimises your vehicle’s engine control unit by adjusting parameters such as fuel delivery, ignition timing, boost pressure, and torque management. This results in improved power, torque, throttle response, and drivability.
PERFORMANCE TUNING
Performance tuning focuses on increasing power and responsiveness while maintaining reliability. Ideal for performance road vehicles, towing applications, and motorsport builds.
Diedericks Race Cars and Tuning is a family business founded in 1963, built on a lifelong passion for motorsport and vehicle development.
