How much boost on stock block evo..with stock turbo..??

so really what is the limit here, i know its prob a coin toss, im going to continue on with the 10.5 on my 03 evo, just wondering if a couple of pounds more makes a difference, as well as will it affect the performance of the turbo?, just kinda wondering what u guys have been pushing it to..on pump gas that is....and i dont wana do either M or A injection either..

22psi tapering to 19psi w/ a tune is generally what most people run on 93 oct....you might be able to get away w/ a little more if you have a good tune

on race gace w/ the proper mods 26-28 psi but then you run into the stock turbo efficiency/max air flow issues
