I don't know to much about what a stock RB25 can handle as far as psi, but I would check out some of the more major boost control companies (blitz, HKS, Apexi) I'm not sure about the cheaper units, but the best is sure to do well, if you wanna spend the dough. The Boost shutoff timer is simply a timer which makes your car idle for another minute or two after you shut off your car. This allows the Turbo to cool off internally, so that you have a steady decrease in temp inside the turbo, as apposed to the hot - cold - hot - cold back and forth, which will evetually kill a good turbo.
Hope that helps.
