it will carry on running

it should rev up as it will sense an air leak i think

its not like an rs turbo when you remove dumpvalve or oil cap, as the breather system on them goes into a metering unit as its all buil it unlike cossies

Nah it will run fine, rev as it would with the d.v on unless it's a small turbo escos and it'll cut out or run rough because of the air flow meter.

shouldn't rev up either as the dump valve is befre throttle body
basicaly your just creating a boost leak,
should run fine but not boost as it should
unless its a late escort with airflow meter

Yes because RST is MFI and the slightest air leak will cause the engine to stall, EFI is different and as said it's before the T/B so in effect it's just like removing the hose. If you remove ISCV that would rev up massively.
