It all goes on your project and what you mean by TUNED?

Are you just putting a kit on the car? Stock ECU, Custom Maps, or Standalone?

Personally I wouldn't use anyone but Eurotech. Brian/Thomas/Chris are some of the best guys to work with and they stand by their work. They took my stock k03 1.8t from 150hp/160lbs to 225whp/300lbs (still retaining my stock turbo, injectors, etc). There are lots of great shops here in Atlanta but I personaly like to go to shops that have done my application numerous times; i know for a fact EPG has done a few setups on vr6 and r32; not including tons 1.8ts, S4, etc.
