60hp more ... sounds fantastic for a 580hp car. Show us the dyno to see where in the power band the new power showed up.

BTW, understeer is not noticeable in Corsa on the 610-4. It behaves different compared to the G and after a while I learnt to drive the car without any understeer. People who only drove it for a few hours cannot adapt.
