I would start with an APR ECU upgrade.

Hmm, I wonder why GIAC is better? From the forums I always see that is more religous than anything else. THe reason why I like APR is that I can switch between stock and various chip programs. Also, they sell a turbo back exhaust (this is for my GTI) and I like the idea of one vendor with several products that go together.

In all seriousness I would like your opionon on the difference since I have not taken the plunge.

Also, Blair and his family are very nice they have done work on my car and done a very good job.
