Just one of many new upgrades from UroTuning. Have to say it was a 3asy install and would have been easier if I did it before all my other upgrades but you will find taking out your battery is the best way and fastest. It works great and makes my GTI even more fun to drive if that's possible. One thing 20% may not seem like enough to many as I didn't to me either but I thought I would try it anyways and was very happy I did. It is the perfect amount that won't cause any damage to your clutch in the future. Hope this helps all of you and enjoy we will see you out there.
