BAC valve... does the VAC line have to see boost?

short and nice question

i'm on the finish line with my T60-1 project... i was wondering if the VAC line running from the BAC valve into the IC piping hast to be behind the turbo outlet?

it would be easier for me to connect the line just before the turbo, after the intake...

so... does the BAC have to see boost?

It doesn't matter cause it shuts off above ~1500RPM.

you made my day

another short question...

i've removed my airpump(because it will not fit after the turbo swap), but i will not remove my ACV (because i want to let the engine bay lock stock)... would it be ok if i plug off the ACV VAC line which goes to the Airpump and thats it?
