Looks lovely mate. I really like it in Red - is it actually called 'Brilliant' or 'Misano'? I do really like the double white stitching on the inside on the flat bottom and on the gear gaitor!
There's not much you need to do tbh....... maybe some MY10 rear lights (slightly darker than current), 10+12mm spacers, lower it by 20mm, larger & darker wheels (19in RS3 Rotors!) and you're there
Re the remap I had my 2.0T done by AMD Woking. I'm fairly impressed with the power increase but a little disappointed they did not send me a certificate as promised - had no response from phonecalls and emails so kinda left a sour taste in the mouth :/
