I don't know what you're talking about. Base score is based on top speed, so if you tune your stock manana to have the same score as a monroe, it should perform similiarly. All tuning types account into this. For example if a car has a traction advantage, it's obvious there's a bigger chance of you losing in a race if you for example chose engine instead.
