Exactly. I know that you can manipulate a mustang dyno pretty easily vs a dynojet one. I know that the numbers it spit out for me that day were way off. I was just doing it for giggles, so it wasn't a big deal to me. I'm exactly like you; tune on one dyno so you know what the differences are. All this driving around to find the dyno that "says" I'm higher than the last one just to have a higher number is stupid IMO. Besides, most of the time numbers are only that...numbers. As long as your happy with your own car, that's what counts. Cars should be built for the owner's liking and not to out do the other guy.Originally Posted by white99gt
