Twin Tuner

This went on a 2005 FLSTCI that had Screamin Eagle II slip-ons installed with a stock air filter. The install was very easy and the instructions easy to follow. No splicing required, giving it a nice sturdy connection. Using the Stage I configuration in the instructions, the throttle was noticeably more responsive and I could feel more power at higher RPMs for longer. Adding a high flow air filter made the power increase even more noticeable. I'm very happy with the results for such a great price.

I have worked in automotive electrics for 20 years, this helped me understand how this worked. It does take some patience hooking it up, but it was just what I need on my 2005 Harley Road Kings lean fuel problem.

Great product for the money and very easy to install. Also there's great YouTube videos that will walk you through the installation, if necessary.
