Actually, that's not necessarily true. It could be a minimal boost leak from a coupler, incorrectly routed vacuum lines, or something else to that matter. So you have a few options to see what's going on. Let's begin diagnosing. What's your vac line setup?
The only thing that causes creep is the wastegate and it's related parts. So if the vac line going to the bottom port if the gate has a leak, you may see some creep. If there is a leak in a coupler you would actually lose boost not creep above wastegate. If the lines were hooked to wrong to the wastegate you would creep so instantly to boost cut it isn't even funny (has happened to me when I was making sure my lines were hooked up correctly way back when I had serious boost creep issues). Another cause although unlikely is the diaphragm in the wastegate is torn. But I would say it's damn likely it's the manifold if many people have boost creep issues on that manifold.

What size wastegate is it? A larger gate will help some, but if the manifold is not designed to flow well to the wastegate a larger gate will only do so much.

A small wastegate spring doesn't cause creep. If it isn't creeping for someone on a larger spring it just means the creep is being somewhat offset by the larger spring. Basically a small spring really tests the manifolds design to see if it can flow well for power and still have very good flow to the wastegate for proper boost control. [MENTION=789]VitViper[/MENTION]
