if you mean redirect air then you'd in essence be causing a vaccum leak. Or something of the sort.
All boost controllers manual or electronic "block" air from the wastegate actuator until a specific pressure has been achieved. Then they let the air into the actuator or actuator line "depending on setup" to actually open the wastegate.

I don't know. My friend's HKS manual boost controller in his Z31 was a bleeder valve. So are aquarium valves. His kit came with 1 T-fitting to splice into the actuator line, and then the 3rd line went to the MBC. From the MBC, the instructions said to route the "dump line" from the MBC into the engine bay.
I was always under the assumption that if you could control the ammount of air that is bieng released, the turbo would have to spool that much more to overcome the air loss, and still actuate the wastegate. If the car runs 7psi stock, then you lose 2 psi through the vaccuum leak, means the actuator would "see" 5psi, but be making 7. So, it would make 2 more psi to overcome that loss, putting the output at 9psi, yet the wastegate is only seeing 7.
