I have a stock 2006 1500HD with the radix and Magnaflow exhaust. I pulled the superchips file off the truck and have made some changes just to the shiftpoints and added electric fans. I would like to see what else I can do with the tune. With my OS I can't run a COS, so what are you guys doing pick up a little more power out of these trucks? I would soon like to do a smaller pulley and cam but I want to know how to tune first.

Thanks
