The LP Performance Manual Boost Controller is just as tuff as they come. Its all-brass construction asures you that it's nearly indestructable. Pressure adjusts from 0-20 psi with the knurled adjustment screw and with a locking nut to ensure the boost stays where you, not the ECU, want it. The controller has Type 302 stainless steel spring and a Type 440C stainless steel ball as a poppet. Turn the boost controller clockwise (making it shorter) to increase boost and counter-clockwise (making it longer) to decrease boost in either Actuator, Integral/Poppet or External style wastegates. The purpose of the LP Performance Manual Boost Controller is to control expensive turbocharger systems at an affordable price. At just $45.00, it is one of the most affordable boost controllers on the market.
If there is any problem with your LP Performance Manual Boost Controller within the first 5 years due to craftsmanship, send it back for a full replacement. For information on purchasing one of these MBC's check the website in signiture.
