Further Engine Mods 3.4L 981 GTS?
Hello, so I have 200 cell cats and performance air filters, have I reached the end of performance mods as an 82mm Plenum is apparently a waste of money and I cannot rebuild my current engine to 3.8L?

As you are from CH, you can do a chiptune which gives you up to 360ps or upgrade to 3.6l: https://t-t-p.de
