IMO say good bye to the regen. To date, I have not used Plum Motors, but hear good things......
A friend of mine is currently redoing his 03 Club Car DS IQ. He will not have regen after, he is buying a new motor/controller from DD motors. I was hoping he would try Plum Quick as I wanted to see how it worked as a comparison. I am already familiar with results using the route he is taking.
