Quick Ship SKU #: PPE-116030000 PPE Boost Increase Valve 01-04 6.6L GM Duramax LB7

You've decided to add some fuel modifications to your 01-04 GM LB7, whether via a programmer, or simply a fueling chip, and that's awesome. However, if you don't increase the amount of air you're getting as well, your engine will run rich. This leads to poor fuel economy and high EGTs or exhaust gas temperatures. With a simple 5-minute installation of Pacific Performance Engineering's Boost Increase Valve, you'll increase your boost pressure from 18-20 psi to 23-25 psi. By adding that additional air flow, you'll not only lower the dreaded exhaust gas temperatures, you'll also increase power and clean up your fuel economy.
