STis Have DSC (3 settings, No icon ON, Green sport, and Yellow off) Then the DCCD to play with too. Then Si drive, Intelligent mode(no positive boost and almost no throttle open), Sport (Small boost, partial throttle open), and Sport# (Full boost and full Throttle opening) Like Jones said in light snow I use DSC in green (yellow for donuts) and will put the DCCD in Auto Minus, and then SI drive Sport mode. In snow when transporting the rug rats in Snow I leave the DSC full on and put the DCCD in full lock AWD and use Intelligent mode in the SI drive.
