Im relatively new to the tuning world and am looking for some help. I have a 2006 chevy silverado with a 6.0 and a sloppy stage 2 cam from michigan motorsports. I got a out of the box tune for the truck when the cam was swapped and it ran good, definetly rich but started and ran fine. Last month i swapped my 4l80e for a rebuilt one and put a jeggs 2800-3200 stall converter. Since the converter install the truck has problems surging and idling. Cam specs are 228/230, 585"/.585" 112 LSA.
