I'm in no hurry to get more power, so I'll let others evaluate any kit that might appear before deciding

I think a lot of people were disapointed with the standard 136hp that the GTI comes with, even though most standard GTIs yield about 140-145hp, once they're equiped with a KN airfilter and a blanket to protect from the engine heat. But check out the forums, and you'll see for your self what has been tried.

Cheers
