    Default 06' 6.0L w/ Magnacharger

    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

    You might want to get a wideband o2 setup and tie it into the efi live so you can see what is going on with air fuel. The tune you have listed currently has a supercharger on it?

    Yes i to have a supercharger on the truck. I do have a wideband O2 on the truck, at idle and cruise it stays around 14.6 at WOT it is around 12.5. The truck also pulls almost 7 degress timing out at WOT. Not sure what to do to correct it, i've read post about it but i don't understand what i need do to correct it.

    Hmmm 12.5:1 for a boosted truck, might want to look at going richer to like 11.2-11.5:1.

    The a/f is lean because it is only like 4-6 PSI very low most likely.
