Boost cut out...........

[WickeD87ShelbyZ]

Guys, I have a 87 shelby z with a t-1 and auto tranny. I am wondering what the factory boost cut off point is. I have been playing with a g-valve trying to get it close, right now I'm at about 11-12 pounds on the factory boost gauge (I know its a factory one), its running fine with no pinging/detonation, always premium gas, nothing else, just wondering at what point the computer is going to cut it off. I am wondering if the previous owner might have a performance cal or computer in it?????????? Thanks
