Company description DNA Tuning is currently expanding our dealer base to cover all regions of the UK and the rest of the world. DNA has developed its proprietary file distribution system to allow its worldwide dealers to benefit from a secure and reliable performance remap supply. Every DNA performance remap will be issued with an 'DNA Tuning official certificate', this is linked to the vehicle's chassis number. For proof of authenticity the customer can at anytime login through the secure DNA Tuning server (using the customer's unique id and password) and access the certificate thus proving that the certificate it is valid. This system is due online this next year.
