Fixing boost creep on an eBay 20g turbocharger

The price of this turbo will make it a popular purchase, so I figured I'd air out some tech about ways to improve it. This thing is not for everybody. I wouldn't feel comfortable bolting it on my car the way it comes out of the box. I could complain about its flaws except that so far absolutely none of them have been a deal-breaker for me. To me it's like an empty canvas. I promise to eat those words if it happens, and share my poop. Usually I can easily correct these flaws myself and so can you.

BUT!

If this thing turns out to perform well with what I do to it... It could easily be a cheap, quick ticket to an 11-second car. Something you could do with a free running 1g, a hacksaw, and about $500 worth of fuel upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a well-modified car... But that being possible speaks volumes for what a DSM can really do.

This is no big deal to me. I'd rather guinea pig my car for you in HD so you guys can decide whether or not you'd spend your money on this. Really it's an experiment because this isn't my daily-driver, and it contributes to building a better Colt.

Tools I used involve:

Scratch awl
Milwaukee model ???? 1/4" straight-shaft electric DIY grinder
Cone and ball-shaped double-cut burs
180 grit high-speed flap wheel
Dremel with a flex-shaft and a tiny 320-grit flap wheel
a zip tie
10mm combination wrench
tiny flat-blade screwdriver (00) for the e-clip on the wastegate
compressed air
