I'm not a tuner myself, so it is not possible for me to provide technical feedback as to why I've given this rating. But I CAN say this tune helped me gold the seasonal with a car I've always wanted to drive successfully, even in GT5, but it didn't handle well. This tune has changed all that; finally the car feels right and is much easier to control through the corners, recover from errors, and slide just the way you want it to. Thank you, Burned_Rubber! Keep up the good work.
