To get to 300 will take more extensive work, cams maybe, intake manifold re-work (like using an N54 manifold), and full custom dyno tuning.
My car makes 252whp NA N52, hoping to make 270whp before digging into cams. Maybe we will do N54 intake cam and remove valvetronic. Already running N54 intake manifold!
