VMS Racing CNC MACHINED billet aluminum boost control valve for the 2001-2004 GM LB7 Duramax turbo diesel engines. This is an easy, effective, and inexpensive way to increase the boost of your LB7 Duramax engine. The VMS Racing boost control valve increases the boost pressure on all LB7 Duramax Diesels engines from the factory 18-20 PSI to approximately 28-30 psi (will vary depending on the engine and mods). This additional boost pressure allows the Duramax engine to burn the additional fuel which is associated with high Horsepower tunes more efficiently and effectively for even more POWER!

The VMS Racing Boost Increase Valve or MAP overboost code eliminator works only on the LB7 Duramax engines. Very easy to installs in under 5 minutes between the turbo and the wastegate. Simply cut 3/4" off the line between the turbine side of the turbo and the wastegate and install the valve with the supplied clamps. Instructions included!
