2012 GS A6 with big cam, American Racing Headers, CAI, 160 thermo, 2800 converter, and tune. I'm about 450 hp at the rear wheel with these mods. Let's assume for the time being, I want to stay naturally aspirated...
What are the next mods you would suggest and in what order, to make sure I'm getting the best bang for the buck? Cylinder heads? Intake manifold? What kind of HP can I get out of each of these mods?
