Say you have two identical boost controllers save one difference, one uses a larger vac input/output. Would it make it more effective at all? Does the size of the vac line make any difference at all (it has to to some extent, that I know)?

I have a blitz sbc-id, and it's vac nipple is about twice the size of the OE boost solenoid, so I have to use a reducer. Should I have a larger nipple welded to the turbo outlet, and somehow make the wg nipple larger to match? Will it make that much difference?

Thanks!

 

It wont make any noticable difference, if any at all.
