Has the tuning Process changed at all since the olden days or does it still require international assistance and overpriced (can't bring myself to spend that much vs other cars I've had, but maybe I'll have to)processes?
FEMTO is still the only unlock method, unfortunately.
Only notable update besides that is JB4 has an upgrade that allows fuel pressure control, which does make JB4 more capable, but still not as good as a proper unlock and tune.
