Satge 2+ how much boost can they hold to redline?

I wanted to put these turbos to a boost test, here is a 29-30 psi across the board pull, I popped a small boost reference hose to the gauge first pull, which tees to AEM map sensor so it shows lower boost after the shift, but its only because the map wasn't seeing full boost as the hose to the gauge popped off. If anyone had any questions on can stage 2+ hold a LOT of boost to redline, they can, and they can do it pretty easily. You take a BP hit as you see its at around 66psi, just slightly over 2:1. Timing for this boost level is pretty damn solid too, holds 10 degrees to redline, after the shift holds 8-9 all the way up. I will take this all day as well. I fixed the hose and you can see on the next run its showing 30 psi in 4th as well as it was getting the full boost signal. Notice how manageable EGT's are even at these boost, and timing levels, the car is pretty happy here. These can actually hold more boost if I want, but 28 tapering to 25 psi seems to be a good curve for BP, turbo longevity, etc, and where I will prob run them daily. Please keep in mind, the less boost you can run to get to your power goals, the longer your turbos will last.
