Default 2003 SWPPED boost help!

So I swapped a 2003 everything into my 1999 RS. Car ran like crap for a long time and finally got most of the bugs out. At present I am loosing boost somewhere I think. The revlimier kicks in at 3500-4000RPMs and I know that's not normal. Also, the higher in the gears I go, the less it takes to get the boost to spike and start jumping around. Like if Im on the highway in 5th, and I floor it, boost will slowly climb to around 10psi on the gauge, around 3500 rpms, and then back off and start climbing again. Back off and start climbing again. Its like the boost builds, then escapes somewhere but I don't know where. Took it to a shop and they told me the pressure tested it and I was loosing boost at my BOV. So I replaced it with a COBB unit. No change in car behavior. Im lost. Any help will be helpful!
