ah..a air pressure regulator will work blake and i have used them for a long time..its in my truck now...but we basically close the valve totally so the waste gate is basicaly seeing no pressure and will not open..if we want it to open a little we crack it open and the boost creep will allow delay the opening of the waste gate...if its total open it acts the same as a stock td waste gate..etc...these regulators are not set to allow say 23 lbs or 17lbs max its not aset it and go ..kinda drive and adjust teh knob so the wastegate reacts the way tyou want it to..but you will find you'll have it closed most of the tiem..you don't see large boost #'s closed unless you have a LOT of fuel and you are WOT all the time..most of the time teh boost is only waht teh engine is able to make from exhaust heat and load so no boost or low ie 5-10lbs even when its shut....you will see what uyou mean when you play with it..its not liek a gasser turbo whern more boost can linchteh engien diesel boost is much different in how th eengine builds it and how it reacts..what teh egt and the boost guage ..more boost will lower teh egt...aloowing more fuel flow..if you want a set teh boost at 24lbs and leeaev it you will have tolookinto another type of boost controller ..probably from a import or a hobb switch setup..laterDeo
