What do I unhook to keep my 1994 Ford Explorer from Cutting out at 85 MPH On the Freeway In rush Hour?

My Blazer had a max speed of 95mph built in to the computer and would cut out whenever I tried to exceed it, in addition the cruise would not set at over 85. I dont think anything short of reprogramming the computer will cure it, besides 95 is crazy fast in a 4x4 suv.
