"the question i have is, will the ABLS take the fun out of this? "

I don't think the ABLS will matter - I've been able to spin up both tires no problem when punching it on slushy roads. Pretty cool actually. All the power seems to get distributed, the 2 back tires just kind of fight over it. Seems to perform about the same as a mechanical limited slip diff.

VDC would probably take the fun out of it, though, as it will cut engine power when IT thinks things are out of hand. However, you can turn off VDC - thank god!

This is based on playing around on slushy and snowy roads, but I imagine it would be the same on gravel/dirt.
