Good to see we have so many people on here excercising 'theory' and clearly knowing more than those that have actually used dyno's.

Using our method, Gary's Evo made within 5bhp at 640bhp on 2 runs that were WEEKS, if not MONTHS apart.

I bet there are only a handful of Dyno's in the country used by people that are more interested in giving what the operators feel are fair and honest (even if sometimes disappointing) figures, but a hundreds used by people that either can't accept a new way of doing things or who operate their dyno to make them look good.
