Default Proper way to dyno an IS-F? (Dyno Chart Inside from Fujita)

Hi,
Just wanted to find out what the proper way to Dyno an IS-F since it has 8 gears and all. Hope this will be useful for other IS-F owners that may want to get their cars dynoed.

Gear ratios there. Says 6th gear is actually 1.000 on the dot.

Like when we spoke the other day....

6th gear is a must and Trac & Vsc disabled is a must..

Also, a trained Technician that knows how to use the Dyno is a must as well..

the sniffer on the dyno is probably off. i highly doubt that it would run that rich for a stock car, hell my turboed civic runs that a/f under boost.

also, dyno the car in a high gear thats gonna put nice numbers on the dyno sheet

nice numbers for that car btw, the torque curve looks killer

That dyno already looks better than the misleading dyno Automobile had . I can't wait to see some 6th gear numbers.

Oh and I went to another dyno place this weekend and he also said the car runs rich too...so unless both places don't know how to figure out the F/A ratio then I don't know what's going on...lol
