The Motec is a great unit; I have used several. If you are going that route, you might want to reconsider doing an end-run on the tuner when purchasing the unit, as you are going to need one (a good tuner) to build the harness and tune it. Not the best way to start the relationship. And, I have had a couple of tuners give me very good pricing on the box, as they know they will make money on the harness and tune.

I know you are not interested in a bunch of ECU recommendations, but the new AEM piggy-back unit should be able to do what ever you need on an OBD2 car unless you are building a full-race system that can run a custom dash and provide data-logging. And, you don't have to touch the throttle-by-wire. I am curious as to the specific functions you want that it won't perform.

Cody has done several turbo OBD2 cars, so you might want to touch base with him on this.
