Before you do! I've become really interested in your problem and did a google search online for possible issues (looked up "car won't go above 3000 rpm"). Here are some possible problems: Bad coil pack, bad gas, killed cylinder, bent valves, miswired ecu, error with MAF sensor.

For some reason, I really think the MAF is the culprit. One guy was able to fix it just by deleting the error code for the MAF (http://my.is/forums/f88/car-wont-go-over-3-000-rpms-fixed-185321/). The code wouldn't reset on its own via disconnecting the battery.

With that in mind, please try and ask the mechanic to use his diagonstic testing reader. Maybe the code will pop up. If it does, then he can delete it and hopefully it'll solve the problem.

I'll keep everyone posted. I'll save the MAF replacement for another date. It's easy enough to replace, and I'm sure it'll come due soon.

Edit: I spoke with the local Porsche indy nearby (http://abauer.com/), and he agreed it's probably damaged wiring, MAF, or added the possibility that it's a fuel pump. I get off work at 3 PM daily (east coast hours, baby) so he agreed to take me into the shop and diagnose it while I'm present. I told him what i've done thus far (fuel filter, precat O2's, cleaned the MAF, disco'd the MAF, new spark plugs, tubes, o rings, new air filter) and he tried to, over the phone, narrow it down, but we agreed it's just time to bring it in.

I'll update y'all tonight with his findings, then we'll see what's going to be the solution.
