Cloned DME. Probably the only viable, safe solution right now.
They contacted me:
We can unlock it inhouse however we will need the cars for 4-5 days.
For a DME unlock and a custom stage 1 ECU tune, we charge:
-DME unlock:£1200+VAT
-Stage 1: £799+VAT
2300 USD. Wish someone in the US offered this service.
