## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Straight forward installation, good software, great supporting documentation.
  

*by D***N on Reviewed in the United States on September 25, 2019*

I bought my Ultra Classic from a friend several years ago and from the day I bought it I was convinced it wasn't running quite right. Intuition was that the Harley ECM was not happy with the gear drive aftermarket cams. I've gone through several attempts to fix the situation mostly when I upgraded the air cleaner and exhaust, even fitting a competitor's tuner, still it wasn't running quite right. Multiple checks of the plugs scared me as the insulators were always just a little too white.Yesterday's installation totally convinced me I was right, yes I had to wring out a few issues (speedo calibration and warm idle RPM)...but, even toodling around town there was a tremendous improvement in ride-ability. Then when I rode the bike on the Interstate...OMG!The sound change was the first clue, the throttle response was the second and the final seat of the pants acceleration clue told me I have nothing more to do to this engine but maintenance.Thank you for a great product!

Well just installed it. Did not tune it yet. Installation was a breeze and kit comes with everything to do so.

Purchased this a couple weeks ago. Very easy to install and set up is pretty easy I had to work out a couple of things but it's all set now. The difference in the bike is like night and day there is plenty of power from the bike now and it's much smoother. I've put a little over 1000 miles on the bike and I'm very pleased with this product. Anybody with a Harley that doesn't have this installed is a fool. Throw away Harley's old technology.
