Here is the deal with dynos.......They are all different and should only be used as a tool. In this case it was used correctly, AS A TOOL.............3 different tunes on the same dyno on the same day. Numbers that come out of different dynos on different days mean NOTHING. The numbers can varry ALOT!!!!
As far as leaving a car "loose" on the dyno......If I left my car loose on the dyno it would spin like a mofo. Hell, we needed 2 people in my trunk to keep it from spinning and it was tight as hell on the dyno. Yeah this specific dyno has a pretty worn out roller but still. With a new roller and loose, my car would still spin bad on the roller.
