how much boost can a stock 7mgte hold??

Agreed. Shimming the waste gate isn't just retarded but it's also hazardous. For every millimeter you shim out the actuator you remove a similar degree of motion from the wastegate's toatal allowable travel distance steadily increasing the risk of boost creep. On the upside, unless you're running a poorly setup FCD, you'll just hit boost cut but that's still no fun and if you're on it hard enough that may not kick in soon enough.

I need to go through the FAQ and remove the references on shimming or annote them all.... Oh goody, more work.

If you want to build a cheap boost controller on your own google "grainger boost controller".

Addendum:
I can't find any FAQ on shimming the wastegate. Anyone care to provide me a link with where they are finding this? I'm sure it's in a thousand and one threads throughout the forum but I'm not going to edit all of those. I just don't want it in the FAQ sections.
