R-Tech all the way. I know everyone on here seems to banter on about them but I have had nothing but good service from the guys there. Helpful and friendly wont remap and run like many other turners out there do. Don't quote me on this but I think its £250 for a remap, full diagnostics and rolling road before and after. AUM so you have the better turbo Ko3s so 210(?) Best bet is to give Pip or Nick a ring - http://www.golfgtiforum.co.uk/index.php?topic=118859.0
80% of your posts are total tripe, as they are mostly replies to sh1te posts created by the morons that, unfortunately this forum attracts.
Thinking of getting mine done too, did send nick a PM a while back, but heard nothing. I too have heard good things about AMD, going over that way this weekend, so may well get it done if not this weekend then pretty soon.
