I finally installed my lexus afm and lucas 550 injectors. I was so happy when cruising and idling my afr at 14.7. So I decided to raise my boost beyond my normal 13 psi fuel cut ( which I really hate). I switched to high boost setting on my profec b which normally will hit fuel. I boosted for a while and my boost gauge reading show that I am still at 13psi. I increased my profec b to max still it showed my max boost at 13 psi. What's wrong here? Why I can't got more than 13psi. I got my turbo off ebay , ct 26 62-1 upgrade. Is my wg spring weak that it open at 13psi? Maybe its time for new turbo.
Can't boost past 13 psi

how much do you boost just off of the WG? (turn the boost controller off)
usully it's difficult to boost over twice what the WG is set to. You cna try a test of disconnecting the line to the WG and see if it goes over (DO THIS CAREFULLY, do a slow pull and watch the boost gauge).
What other upgrades do you have?

Boost of wg is 6psi. My other upgrade is the typical bolt on - 2.5 hardpide, 26x13x3 spearco style ic, HKS ssqv bov with stock bov , K&n, defcon downpipe, 3" test pipe and Hks drager. I need to pressure test my car looking for boost leak. My lowest afr is 12.3 at 13 psi with lex afm/ 550.
