I do my own mapping on a rolling road dyno. Martin Sansom at Sanspeed operates the dyno and 'drives' the car and I do the mapping. If we need any mechanical changes like cam timing, we do that ourselves too.
Only major drawback I can think of over an engine dyno is the lack of proper cooling for a turbo car. We are going to plumb in an air/water cooler next time to keep air charge temps in the range we see on track.
