Speed is sensed at the trans, abs is at the diff (3 channel) or at the wheels if you have tcs (4 channel). Weird problem though.

You've given far too little info. Is the car 3 or 4 channel, have you done anything to see if it actually is an 02? What was done in the computer.

To me it sounds electrical or computer related (i can't help at all with that), but the bogging could be due to killing an 02. I have had them die on hard throttle before.
