The mustang dyno by me is like a rolling road. It will apply it's brakes to a certian percent to give resistance/drag depending on the vehicle weight.

I put down 220whp/230wtq stock and 262whp/286wtq stage II. Obviously those numbers are FAR from impressive, but the car can still do 12.9 in the 1/4 and whip you back in your seat.

A dyno should be used as a tuning tool, and used to compare numbers vs stock form. the 262whp/286 means nothing to me. gaining 42whp and 56wtq while stage two on the same dyno means something to me.

Im no dyno expert and i kinda rambled, hope it somewhat helps you.
Very goog post!
