On internal wastesgates you can raise preset psi but you cannot lower below the set psi level on external wastegate you can lower the preset psi but you cannot raise it above the set psi correct?
 
the spring in the waste gate is the LOWEST boost setting you can run.

Boost controllers ONLY go UP, and are good for about DOUBLE the spring in the gate.
