Now considering the speeds reached (175mph), I certainly would NOT want to being checking that out on the road
.
When i said `dyno`, i actually meant to say rolling road.
No i did mean to say mapping. Ive heard some tuners say they do most of the map on the rolling road then the very top end(high rpm/max boost) is done on the road while flat in fifth!
I would have thought that a good rolling road would have enough braking effect to load the car enough at 175mph. Is it due to lack of airflow on a rolling road to keep temps down?
