Default possible fuel cut past 15psi

He guys, so decided to turn the boost up on my sr. Have been running 15psi for a while turned it up like just pass that, 16 or 17psi. Pretty sure its like fuel cut or something, it like spits and misfires. A/f gauge says like 11.2 and fluctuates to like 12.7 and back when stumbling and misfirig. So I guess my question is how can I find out what is causing my problem, like injectors maf etc. I feel like all my mods should not max out that soon. Any help is great thanks joe.
