I just installed 799 heads and http://www.compcams.com/Cam_Specs/Ca...csid=1399&sb=0 in my 2004 2500 6.0L. I bought a diablo tuner before i knew any better. Kinda tapped out on funds for now. Any ideas on what i should change with the tuner i have? Also has anyone got a diablo tune through nelson? Any idea on the cost and how good they are? Thanks
