No, you definately can't go down. You're going to have to find a lighter spring or somehow ghetto rig that one.

if you have the vafc, then you dont need the fmu and missing link.
doesn't matter that it's a dohc zc.
what is the stock wastegate set to?

you can try getting another wastegate actuator from another turbo or you can do the carb spring trick.
use a spring in it's place to hold the flapper closed. if it opens to soon, stretch the spring more or add a stronger one.
straight hmt.

drill a hole in your manifold. Each 1/4" hole is -1 psi.

i cut an acuator arm and threaded both ends before. used a hollow metal bar and some nuts to adjust the length worked great and cheap.
