Noob question.
First Porsche, wasn't even out of dealership parkinglot and I was already looking online at ways to customize it.
Think I have a handle on what was in the x51 package. Didn't see any mention on airflow, and the filter case looks stock. My question is, adding a conical filter, will I still see the increase in HP and throater sound? Has the x-51 package tapped out the increase in performance and sound?
Incidentally, the car threw an engine light on day two of ownership. (Dealer has been great trying to make it right, that's not the issue). Feels like a misfire, but they have already changed plugs and coils, as well as well mass air flow sensor. I'm now 2 more hours in on the engine and the light came back, it rode really rough for a while, now feels fine but the light is still there. Shop is looking into it, but they seem like they are struggling to find the problem. Any thoughts?
Thanks guys
