Why do autos have a vacuum chamber for the double throttle?

Not sure - but if you notice there is also an additional check valve on the inlet for the double throttle mechanism for the auto.
I had asked about the purpose of the check valve a while back - but I suppose if you are to keep a vacuum chamber charged, it makes perfect sense to have a check valve.
Not to hijack the thread - but I'm curious too.

^^ Maybe
BUT
The automatic's double throttle solenoid is still piped to the turbo inlet duct whereas the manual is vented to the atmosphere with a filter only. Wouldn't the automatic double throttle still be in vacuum all the time anyway?
SO here is my theory:
The automatic utilizes the double throttle vacuum tank while the engine is cranking and the TID isn't seeing vacuum?
I dunno.
