When I unplugged the MAF the car wouldn’t fire at all.
I reset the codes and the o2 sensor codes went away but everything else remained. I highly doubt this is something as simple as a fuse but I suppose I should check them just for good measure

Interesting that your car will not start with the MAF unplugged.
Every Boxster I have heard of will run with the MAF unplugged.
You can check your MAF wiring with a Multi Meter so you could check it's ground that way.
You can also bring it up on your Durametric and look at voltage and if you know what to look for and how to compare it to other signals like throttle position you can test it's function.
You would have to look at the wiring schematics to figure out pin outs and grounds for various circuits.
Pin outs:
On the harness connection to the ecu each wire has a corresponding connecting point to the ecu.
those corresponding points are called pin outs....they are also coded similar to your fuse box...so say your looking for fuse A1 so that would be row A and 1 would be the first fuse in row A... Harness connections are set up a similar way.
Try recalibrating your E-gas (gas pedal) see if that will do anything to your throttle position codes and your potentiometer codes.
