BOOST CONTROL VALVE KIT

sure settings. A leaking and inconsistent boost control valve will cause a 10-30 horse-
power loss in performance.The all aluminum constructed High Performance R&D
Adjustable Valve offers perfect sealing and precise adjustment for consistent boost
pressure control.The valve comes factory preset for 16 pounds boost and is adjustable
up to 22 pounds.The valve mounts directly to the OEM location with a billet aluminum
adaptor that offers boss locations that can be used to install a boost gauge. For those
with a reprogrammed R&D ECU, this is a must have upgrade to allow the ECU to per-
form to full potential. kit includes all gaskets, hardware and installation instructions.
