depends on where you live,  what kind of carb you have to get.  does  your state allow other carbs and still pass inspection?  do you have a  visual or a computer inspection of the exhaust?
if you can use  any carb,  you do not have to get one with the electronic controls.  you  can do the nutter and it will run better then without it being done  since the computer will not be trying to adjust for the electronic carb  anymore,  if you get a different carb.
