I think finding right hardware is not an issue ...

ESS Tuning is at present searching for a 1M owner who is interested in testing their new turbo upgrade. Anyone interested in sending their car to ESS for development can shoot me a PM, and I can make the necessary arrangements.

ESS can get access to 1M pretty much at any time
I think they are a bit busy with all the other projects they are working on ...
