Default BCS Trick?

i just tried the BCS trick were u switch the lower vacuum hose. Just to see what would happen, cause i think mine might be bad. I had a inter mitten SES light before the trick and now it has not come back on. I know i not supossed to drive alot like the way it is but im gonna drive it home(about 10 miles) and see if the light stays off. If it does should i replace the BCS and or the BCA?

Typically that would indicate a BCS failure.

The added boost by tricking this could cause problems since it can't dump boost to shift or when you hit a fuel cut off.
