pull the wastegate line off and see if the boost starts to spike (let off the gas at 25 of course). This will help you narrow down the possibilities.

I'm running the green ported and polished with buschur hp wastegate actuator..min boost is 21 psi for that actuator..I'm running map o2 dump...I checked all vaccum and lines..did found one leak and fixed..I thought I might have reverse the hook up at the control valve but its hooked up correctly...com to actuator and NO to turbo...I tried raising the set boost, start boost, gain ect higher but still boosted 21

finally got it fixed! i tested everything and was fine... turned out to be the connector between the boost control valve and the control unit was loose..which i wired it behind the dash...was pain in the *** to find..but now its boosting good!
