Do it mate, you'll love it
Just a word of warning the remap will weed out any parts that are on their last legs (coil packs, the clutch in my case lol) so be prepared for this

You're best of finding a breaking TT or Skoda Octavia to get the brakes off, shouldn't cost too much
Give R-Tech a bell and I'm sure one of them will tell you if you need anything else to go with the remap
