Default way to limit boost?

ive got a 94 2500 ram the mods r a 4k gsk, no plate, tuned afc, 4in exhaust, and afe intake, stock turbo btw. i have the wastegate plugged so i can boost a little more and so theres not as much turbo lag, if i kept my foot in it i could easily blow the head gasket bc of the amount of boost, im wanting to know if theres a way to limit the boost at about 35 lbs. im thinkin maybe putting sort of dial on the end instead of the bolt that i have stuck in it to partially plug it off but not all the way ya think that would work?

i used to have a lockable air pressure regulator from grainger and ran it inline with the wastegate and set it to pop open at what ever psi i wanted it to.
