I now have GIAC Stage II on my 335i and dont regret it at all. The only question would be is there a dealer close to your location so you can go in for the install.
I believe the GIAC map switcher has a stock "simulation" map. Not the actual stock tune. GIAC is a great tune though. Just a bit weak and the latest Cobb maps are pretty freaking smooth.
