we have our computers sent from Australia to Germany for FVD to do the work.
If your US spec cars are down on hp for smog requirements, sending the computer away is probably a good thing.
Another option would be to piggy-back a Motec or Autronic onto your factory computer.
...they can be bought ex Australia, and our currency exchange is a lot more favourable.
Thanks Tom

Its slowly getting there, wish I had more time to spend on it.
