I have a '05 a4 quattro s line with the 3.0 in it. I want to either get a supercharger kit or turbo kit for it, however for example when on ecs tuning I go to the b6 chassis drop down menu, there is no 3.0 v6 option. And just to see I looked at b5 chassis and no 3.0 there. What is going on, this happened on other websites too.
