Boost Controller

I have a sr20det s14 engine with 740cc injector computer tune 3in exhuast and a gt3076r bottom mount turbo. Any just got a Grerrdy Profec B spec 2 boost controller. I was wondering about the settings. I want to run about 19 psi. I've been messing with it just for a day or so. If anbody has close to the same set up or knows how to set it right your help would be very appreciated. Thanks in advance!
