Yes! bootmod3 is the only flash solution where the license can be resold and/or transferred to a new VIN when/if you decide to move on for any reason. Having re-sale value is a great advantage to choosing bootmod3 for your tuning which is NOT available with any other flash tune.

  • License transfer is restricted to the original order purchase and buyer. Transferred licenses cannot be transferred more than once.
  • Any previously purchased OTS maps and custom tunes by the original buyer are not transferrable due to map data incompatibilities between cars.
  • To transfer a license you need to flash the car with the Stock Tune AND DME RELOCKED using bootmod3 interface. Further information on the transfer process can be found here.

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!
