I am glad that someone finally commented on this chip....I am very impressed with this product, I picked up my Unichip from TurboXS yesterday and installed it in all of 20min (30 if you include having to fiddle with the restrictor hose). The chip is just like the title of this post "The Shiznit", for all of those people leary of spending $700 on this peace of art work, GO GET ON THE LIST and get one! Take my word for it, this is probably the best bit of money you could spend for your baby/WRX. I am not trying to say that no one such as Cobb, or Metric's chip isn't a good product, I am just speaking from my experience, and for the money you can't beat it.
Fortunatly I am only a half an hour away from TurboXS, but the greatest feature of the Unichip is the tunability, (not to mention it comes out in a jiffy, for those worried about SOA) any thing you do to you car, the Unichip can be retuned farely easy.
The perfornance side of things has already been explaned from the above reviewies, but to sum it up this Unichip really makes the car perform like it should of from the factory...Like the "Rally inspired WRX"
Thanks for listning, ~ Brian
