      Nice.

      I have to say they stepped up their game. I pulled out my old crane high 4. After 15 yrs! Looks like S&S up the quality.

    • Top critical review

      Junk would not fit my motor. used a grinder to make it work.

      It would not fit, called the supplier and they made me jump thru hoops, so I called S&S same thing. I ended the problem with a grinder so it would fit. what a joke. i had 4 different type of ingintion on that bike and they all fit no problem. i have a 100 Inch revtech motor. save your money and buy something else.

    • All true

      Yes this module is an excellent addition to you bike if you're looking for performance in speed or fuel economy it's easy to have one or the other with a couple of switches and you're on your way, I'm hooked into a s&s 96" motor n and yes my bike was fast but now it's for real fast! I would recommend it to anyone.

      Simple to hook up! Instructions were spot on! Does not come with rotor cup, but a great buy none the less.

    • Excellent product and value for money.

      A great improvement to the stock tuner. Fully adjustable with notable power increases. Works well with an upgraded cam, coil and breather reed valve. It is of high quality and built to last.
