his friends was hitting 25psi..After watching the video,I see that he never did..And after it reached 24 it began to drop off till it reached 20 at which time he shut it down..Otherwise it probably would have continued to drop off..You don't have to show me a compressor map,I'm with you..I have never heard of anyone reaching 25 psi on stock turbos. And after watching that vidoe it still is the case..Did you notice that everytime boost started to drop off he let off the gas??This is just a case of someone not knowing or has been misinformed as to what the stock turbo is capable of..
