Clubhead,
Call Evo. You're assuming they'll tell to piss off. But on the other hand, they've wrenched on a lot of Porsches and might just give you the answer without having to "guess", which is what all of us are doing here.
With that said, your idle will stumble when you take out the filter. It is suddenly seeing a ton more of unimpeded air and the computer doesn't know what to do. I used to take the filter out of my M3, run the car and shoot injector cleaner in to clean out the idle sensor, etc. With one hand on the throttle linkage, it would still buck like a bronco. So what you're seeing isn't out of the ordinary.
I would attack the problem with:
1. Call Evo.
2. Run dyno and get a/f readings.
