Greddy Profec B Spec II

[9394]

Anyone know if the Greddy Profec B Spec II displays boost even when not in use? Obviously if I set the boost to 10PSI, the controller displays the boost, but if I leave the stock boost, does it display that as well?

I don't really get what you mean, i am using profec b, it display real time boost pressure, if u turn off the controller the display will still display the real time boost.
