Anyone have electronic turbo boost control valves fitted?

I read an article which stated these were a factory fitted option. I don't recall such a thing and nothing comes up in any of my price lists or factory comms.

Does anyone have these fitted, where are they positioned and what's been the benefit? And did you remove the (then redundant) mechanical valce directly connected to your turbo?

Just interested.

Thanks Andy. Of course this was Lee (Noble's) original idea - to use the switch for this reason. What confused me was an article I read which stated that this was a factory option. Seems it isn't.
