Chassis Dyno Questions

Just keep in mind that the tune that made the best power might not be the tune that is the most drivable. The dyno doesn't really tell you how your car will act in traffic or on a day to day basis. Nothing against dynos and I wouldn't mind putting my toy on one, but friends of mine have swore off them and strictly test then tune. Also some dyno makes give lower or higher results I think mustang dynos are known to be a little low.
