Llandow Tuning specialises in vehicle modifications. Our work often involves altering a vehicle from its factory specifications, typically for motorsport or fast road use.
All modifications and tuning are carried out at the owner's risk. Customers should fully understand and accept these risks before work begins.
Dyno and rolling road use is at the owner's risk. Any damage caused to the dyno, dyno cell, or due to fluid spills must be paid for before the vehicle is released.
It is the customer's responsibility to ensure the vehicle is ready for tuning/dyno time and free from fluid leaks unless otherwise agreed in writing beforehand.
GDPR Policy - All work is conducted under the assumption that the customer has read and agreed to our Terms and Conditions and reviewed our FAQ section, which addresses the most common queries.
