Our maps are proven time and time again as reliable and effective. Even though we can offer incredible gains in power and torque, we also believe in safe and sensible tuning - that's why our customers return time and time again. We offer a lifetime warranty against any software malfunctions, furthermore, all original maps are backed up on a dedicated server allowing the vehicle to be reverted back to the original format at any point in the future.

Before carrying out any remapping we always carry out a full diagnostic health check to ensure the vehicle is in the correct state of health and no current engine issues are present. We believe that driveability and reliability is as important as performance and therefore when you choose to tune with Avon Tuning you can rest assured that your vehicle is in safe hands.
