Does anyone out there have a stock dyno sheet for the 2007 5.3L vortec , with active fuel management and a 3.73 rear differential?(A Silverado 1500 crew 4x4 18 inch wheels if that makes a difference) I can find peak HP and and torque numbers but not not the powerband graph itself. I have found graphs for older years such as 2000, 2002, 2003 but i am quite sure the numbers have improved since then.
