Given I've spent five years mapping cars on the road and using various far less sophisticated systems than the EMU Black, I feel I should be able to get Monty reaching his full potential without a rolling road, although I must say a dyno is still the ultimate tuning tool and nothing will ever change that.
I was thinking along the lines of rolling road to provide hp/torque figures rather than tuning Dave. A group of us are booked with Revivals near Duxford to see just that next month.
