Very clean Sierra with a 2.9L Whipple Superchargers is back for more boost. We added a smaller upper pulley going from a 3.25" down to a 2.85", AlkyControl Meth Kit and some spice via Phoenix Performance Calibration- picking up a decent amount of power!

627 whp / 685 ft.lbs
(~estimated 784 HP at the crankshaft, before driveline loss)
Picking up +47whp and +68ft.lbs!
