I know it's weired the other graphs are ok. I thought i would put that one up as it was me in the car & they were trying out some of the dyno's extras out. This one held you back for what seemed like an age even with your foot down. Once you reached a pre set speed off you went. It also has settings for drag cars,it is a clever thing. My car will be back on the road today if i can get hold of this Rs belt.
