How much are you losing? It's normal to spike the boost then it will settle down again.
If you are going just by the feel of the car, then after 6500RPM the car doesn't accelerate as fast in my opinion.

in 2nd-5th the boost gauge goes to 14psi then around 5000rpm's it starts to loose boost it goes to around 9-10psi. This really suck's

I take it your car is stock?

If so, that is what it's supposed to do. That keeps your car from running lean at high RPM's.

Then it's stock for our discussion here. None of those parts will effect the boost control on the car. It's fine.

An MBC will help that out a great deal. Please keep it around 15psi though. More is not better when it comes to boost.

*Clears Throat* I agree with you that the UTEC is not God, for that matter no Engine Management is. Why do ecutek when you can go with AccessECU for practically half the price, with the only cost difference being one was built and designed "in-house".

ECU reflash-management is the way to go, would have been a better way to put it.

www.ecutek.com and www.cobbtuning.com

I'd try to put the stock valve back on and see what happens. I couldn't tell if i was just getting used to the car or if it was just slower so I datalogged the car and found that my rfl valve was leaking almost 2psi after 5500rpm compared to the stock valve even with 6 washers in it.
