Mark at Exotech just did RHD throttle bodies, COP, and a MaxxECU on my 3 liter for my 914. It's wild to just reach in and hit the start button. The car starts immediately and just idles. He has to finish tuning it, but it was really fun at Summit Point this weekend!
The Maxx is really powerful. I have future plans for DBW, but that is a ways out.
