You need to only remove the vac pipe to the dump valve, you'll still need to have a vac pipe to the boost gauge.
So if you remove the t piece, you'll need either a straight through connection to join the two pipes, or a new piece from the manifold to the gauge.
And if you've got an escort Rst on mfi, you won't get chatter as the metering unit has a flap in it that closes!
