Very nice!! Let us know how you get on with the remap, would be interested myself and good to know there is somewhere in NI who can tune the GTI 
Yeah the guys at autotune Ballymena are great, cant speak highly enough of them. Especially good that if you want that they can come to your house and remap it on your driveway using their laptop based system. They have a full rolling road setup on their site too.
