does the turbo boost control solenoid on s5 turbos prevent the wastegate from seeing a signal at all until the turbo is making full boost (to accelerate spool-up) or just regulate the maximum amount of boost made? it's not clear in the FSM.
if only the latter, i'm thinking of rigging a ghetto boost controller with a Hobbs-type switch.
thoughts/info?

the ecu can tell the boost controller how much boost to run. you don't have to use its very inefficient!!!! i would suggest a manual controller like http://www.dawesdevices.com
just leave the solenoid hooked up but don't hook up any vacuum lines

it's a bleed type... ball and spring is much better.
anyone running an FCD should not be using the stock boost contoller... I'm pretty sure it'll creep higher then not having one at all.

you could also get http://www.boostvalve.com
if you have $200 to spend you can get the greddy TVVC i have one of those sitting in my room

Scott 89t2: afaik the FCD doesn't cause boost creep, it just allows people to run their engine with mods that cause boost creep for a little longer before blowing things up

the solenoid only works with a stock exhaust its TINY! when you put exhaust on it can't do anything. i guess you have seen a greddy profec solenoid its bigger than a rubix cube!
