Anyone have electronic turbo boost control valves fitted?

[AMG Merc]

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.

Sounds like blurb for the boost control solenoid? Some people wire the redundant dash switch to give hi/low boost. Low being the actuator (mechanical) controlled boost.

These are starting to come in on OEMs. It gives you greater control of the turbo(s).

Probably won't see them aftermarket for a little while and you can do most of what they can do with a good electronic boost controller (boost by gear, etc.).

Some of the Rossions have a programmable boost controller with up to 10 self programmable settings that you can toggle between. Made by Gizzmo.

I think it was an option on marelli ecu, its standard on the MBE... its a vauxhall VXR part and is effectively an electronic bleed valve, allows the cars to make 0.7bar when they have a 0.3bar wastegate spring... the MBE controls the amount of bleed via the map.
The valve is bolted to the manifold on the 3.0L engine.

Some people wire in a switch which effectively turns off the valve so no 'bleed' occurs and thus the engine only makes wastegate boost i.e. 0.3bar instead of 0.7bar on a stock 3.0L.... of cause its much more common on modified cars so they have a low boost option.

I know some cars came from the factory with the switch in the dash (£1 item) but never heard of one that was actually wired in from factory although would make sense odd one was otherwise why would some have the switch?

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.
