I'm looking for soures and ideas for performance mods for the 3.2 V6 2007 A6Q?

 

There really isn't any performance parts out for that engine right now. You could make yourself a custom exhaust which might get you a few horse power, but thats about it as of yet. They might make a supercharger for it, but its gonna be pricey because of the direct injection.

 

I think Unitronic has a chip +13hp/+15tq

H&R makes springs

and you can upgrade to S6 sway bars
