The only one I know is as said a "Two stage boost control" this is simply a switch wired into the earth of the amal valve which goes to the ECU, when the switch is closed you run maximum boost but with it open you run lower boost.

and that is how my other car is set up switch wired to amal valve but this one the wire from the switch goes to the ecu, is the amal valve wired to the ecu also? maybe they wired it there rather than running it down the engine bay to the amal valve?
