Welcome ! You can change the pulley size on the L or the HD to increase boost. Yes, you can achieve similar, or exceed, boost levels on the HD as the stock L. You need to buy the pulley, have a chip/tuner programmed with the matching proper tune, and change the plugs. You can buy one pulley with a diameter for a given boost level or buy an interchangeable pulley system which allows several pulleys to be exchanged on the same hub for a variety of boost levels.
