2006 Gmc Sierra Diesel Six Gun Bundle Engine
|
Our guinea pig for the Banks Six-Gun Bundle is an '06 GMC Sierra 2500HD equipped with a 6.6L LBZ Duramax Turbodiesel. The truck has been doing a great job towing a pretty heavy trailer, but the pain at the pump was getting out of hand. After the goodies were in place the truck had all kinds of power on tap, and we saw a gain of 2.2 mpg on the highway. View Related Article
