PCIII is the way to go. Allows for maximum adjustability and tunability. You won't notice the difference until you get the bike dyno tuned. No two bikes are the same and all parts mesh in different ways.

Spend the money once and get the dyno tune done and you will be very happy.

Ride on!

 

I had the same problem with my PCIII USB, hard starting and a misfire between 1100 and 1800 RPM. The hard starting was a simple reprograming problem and the misfire was the acc pump program needed to be turned off and the cylinder trim set to 0.

Bike now runs great from idle to redline! And no hard start!

Contact Power Commander (phone or e-mail) and they will walk you through it. You will need to download their latest software update before you start.

They are great folks to work with.

Just picked up my 2006 Ultra, Big Sucker, Super trapp slip-ons, new 25' injectors, power commander, and had it dyno'd. What a difference. great improvement, mid range greatly improved. Do half my riding two up. Looking forward to a long group ride Sunday. hp 78 tor 77.5. Highly recommend this upgrade.

Also consider a mild cam for your passing and 2 up needs.
