check for leaks its less than 10 bucks to make a good boost leak tester.
also what size exhaust are you running? we had a boosted d16z6 with a greddy kit that had a really small cat and it was killing the hp and boost levels. wouldn;t boost over 6lbs because of the cat.

im running a 3inch xhaust piping all the way thru,so i dun tink its the xhaust system. funny thing is,the car will boost higher,just that it wt hold n drop to say 2-3psi at 7000rpm onwards.

i would unhook the boost controller and try that to see if it holds the steady pressure. also where is the pressure line to your wastegate comming from? if its from the compressor try running it from somewhere on the intake manifold. like the brake booster or fuel pressure regulator vacume line.
