TMC Motorsport / Bombardone back box - loss of torque myth
« on: February 24, 2015, 08:00:53 AM »
Hi guys. I'm due to purchase the Bombardone back box. I've heard nothing but good reports apart from one or two people saying that changing to a straight through back box can result in a loss of torque. Is this just a myth? How can a change of back box cause this if it is true?
