Its all controlled by changing either the boost valve diameter , the pressure regulator spring then fine tuning it from there with regulator spacers (horseshoes or 3/8 washers) of different thicknesses.
There is a regulator setup available for constant line pressure applications that allow you to adjust the pressure via a screw from the boost valve area.
yes its a manual valve body with a tci brake
behind a 1000+ hp twin turbo small block chevy with somewhere around 4000rpm stall(havent figured out what stall we need yet)
200 psi sounds about right. There are several spring/booster combo's that will get you there or Griner makes an adjustable regulator if you decide to go that way.
