If you have it stick with it. I still have my whole setup, just haven't gotten around to installing it yet. I got lucky and scored the trigger bracket, wheel and HB here in the parts section. The nice thing about the tec2 is you can likely find a tuner almost anywhere. That might be true now for the MS too with how popular it's become.
I think the reason you don't find much support around here is because of the cost. Most of us are budget minded. I'm just plain old cheap!
Edit:
Yeah I just realized you have the tec2. Don't forget you'll need an old PC to be able to communicate with it too. I'm actually looking at the SW sitting on my desk in floppy format!
