Perhaps the original poster is talking about power reduction effects? The problem arises when you are turning into or through traffic and you lose traction. The various traction systems will reduce power to regain traction. The problem is, you now don't have the power to make that left turn in front of the 18 wheeler bearing down on you, you are moving at 1/4 speed. I have had this happen, not in a gmt 360, but I have had it happen. Its pretty damn scary when it happens too. Stabilitrac, and other manufacturers similar systems, are amazing. They help you correct problems that SHOULD have put you in the ditch. I think the thing to remember is that the vast majority of time it will help you. I would only turn mine off if I was off roading.............
