Boost problem. Engine won't hold boost.
 
I have a DA with and ITR swap with a b16 cable tranny (4.40 FD), i recently got the homemade turbo kit put together and tuned to a safe but close tune with CHROME to 10 psi...
My problem from a boost leak was that the boost was falling off in higher RPMs, it would spike to 10 psi, then fall back to 6 or 5 and try to hold there....
I pressure tested the piping and found a small hole around the BOV and fixed it. After the fix there were NO leaks in the piping whatsoever...now i only get 7 psi and thats only in higher gears like 4th or 5th, the higher the rpms the more the boost drops, it falls right back to around 5...
1st 2nd and 3rd gear the boost gets a little higher but nothing above 5 psi, which i kind of understand cause there's more load in higher gears...
I've eleminated the BOV cause i tried a different one...nothing
I've eliminated the Wastegate, we completely disconnected vacuum from it and the car ran worse...
I have a boost controller hooked up...still falls off
I'm just stumper now and need more ideas...any help would be nice...

Just a friendly warning, Josh... they are the sort of girls who'd double team a guy like Kalam:
