On a stock car in 3rd gear at WOT, the boost should shoot back up to 10 after the 4.5k transition. It will then slowly roll off to 8 or so at redline. If your's is dropping to 8 too fast, you could have boost leaks or a partially clogged pre- or main-cat. Or some other difficult to diagnose problem.

Roll off to 8 at redline??? Mine stays at 10 all the way to 7500 rpm. You might want to check your turbo system.

Do you have any mods Trex? I think a completely stock car naturally rolls off to around 8 near redline.

does it go from 10-8-8 or 10-8-10-9-8, pretty much does it build back up boost after the 2nd one kicks in?

It should recover from the dip to 8 at the transition almost immediately.
