On road tuning vs dyno tuning

[quicksilver7]

like extremelo mentioned. It depends on what dynamometer ur car is tuned with. If dynoed on Chassis Dyno/Load Dyno(Dyno Dynamics, Mustang Dyno), the wheels have retarder that produces load onto your wheels just like on the road... The load can even change. Higher load = uphill, lower load = flat road.

Whereas Inertia Dyno(Dynojet, Dastek Dyno) wheels are free running wheels. So, on the real loaded scenario, the AFR will be slightly different.

Cool! Thanks for the good explanation :D What are some of the shops that use the Chassis Dyno/Load Dyno(Dyno Dynamics, Mustang Dyno)?
