2009 LTZ with 5.3 / 6L80E


The truck is a very nice daily driver, but was lacking a few things so the goal was to increase HP/TQ as well as appearance/handling while not compromising drivability or the ride. We chose the Magnuson TVS route combined with some suspension upgrades and the customer is more then pleased with the results
