how does a remapped cr vrs octavia compair to a standard fabia 2 vrs performance wise? no reason just curious. people say a remapped cr is quicker then a remapped mk 1 fabia but not heard much comparison to a mk 2

Well, I know for a fact that a remapped Yeti 2.0 170 CR is very close in speed on a track to a stock mk2 Fabia VRS.

 

You'd lose not having 4x4, like the Fabia.  But gain in the aerodynamics over the Yeti.  So I suspect there would be very little in it.

 

Probably such a small margin it would depend on the driver IMO.
