Is it an inertia dyno? Inertia Dyno's are not the not adjustable and not the most accurate if you're only interested in peak hp output. If you strap it down correctly and feed the throttle the car will do it's thing> Take it easy!! Many vehicles have been damaged by overzealous use when there's a crown watching!
