Do you have a/c? Also what settings you using for idling? If I could figure those out perfectly i would gladly get rid of my stock ecu.

No A/C, my idle is working but not as well as I would like. Will post my msq later on.

One quick and really need answer to question. How do you configure the RAD FAN, I can't seem to get to the rad fan on settings in megatune, they are greyed out. And I REALLY need a ran fan asap. Can't seem to find it anywhere.

You have to select the fan output in the outputs menu under basic settings. Also, you need a relay circuit to run it, like the mod kit diyautotune sells.
