I'm struggling to think of a bushing issue that would make it always pull to one side regardless of acceleration v. braking, that wouldn't also be apparent in static alignment.

Edit: A bump steer kit wouldn't be the fix, when that's the issue you'll feel the car pull every which way depending on road surface, it's predictably chaotic. I'd imagine the guy has other Porsches in the shop, should have a spare set of wheels and tires he could throw on there.
