Yes, that will keep the boost to whatever you set it at with the adjustable elbow. You can actually just put a boost elbow in the hose coming from the turbo and unplug the electronic control on the turbo instead of running a tube all the way from the intake. The only bad thing about unplugging the control, is on some trucks, not all, it will set the check engine light, the way around that is to call Piers, the sell a little box with some type of resistor in it that plugs to the factory plug and keeps the ecm happy. You MUST unplug this plug for this to work properly or the ecm will close this boost signal port and your elbow will be useless.
