I also posted this at nopistons, so I apologize if you've read it twice now...

Here's what I get at WOT in 3rd

0-5500 rpm: boost steadily decreasing from 13psi to 10psi
5500 rpm: 5 psi
5500 rpm-redline: 6psi

With the high initial boost, I'm thinking that the wastegate or charge relief might be the problem. The low secondary could be just a leak somewhere, but the late transition is very confusing. Anyone experience a similar problem? Any suggestions would be much appreciated. Thanks.

(my mods: intake, smic, cb)

By the way, I have run many tests on the precontrol system and it is working fine.

I have also read the information here:

which was very useful, but did not address my specific problem

Might the fact that I live at 7000 ft above sea level affect the transition point?

Can anyone think of anything that might affect the transition point?
