Rod adjustment is not going to do anything if the exhaust gases can't flow well enough through the small 02 housing WG opening. You could drive around all day with the WG 100% open and still have the issue.
We've seen half a dozen megan/ebay 02 housings cause creep, the solid fix was always a better 02 housing or seeing if the WG hole can be ported enough without compromising the unit...

Thanks for everyones help. I will be pulling it off during Thanksgiving. I e-mailed megan to see about warranty but if not does anyone have advice on exactly what/ how much to port.
I do not have a grinder only an electric drill

There is a thread about porting the O2 Hsgs. Maybe someone will post the link. Otherwise, I kind of recall something about grinding the existing hole out to about the diameter of a golf ball.

Lol I talked to Megan Racing and they told me there was no way there o2 housing was the cause. They said I needed an electric boost controller and that it was creeping because I had the resonated test pipe.
Time to start porting

I like how Megan Racing is avoiding the issue by blaming another part. An electronic boost control will work, but that's just a bandaid. Port the **** then lets see some boost graph comparisons.

Boost creep is when the WG opens due to pressure on the turbine as it looses efficiency with increasing pumping rates (higher rpm). Boost will drop. You can tighten the WGA to hold it more but it will spike at lower RPM and engine probably won't be happy at all near redline. Thats boost creep. You have spiking, the boost control system probably needs an overhaul or cleaner configuration
