Review on 🏍️ Vance & Hines Fuelpak FP3 Autotuner Fuel Management Software: Performance Tuning for 4-Pin Harleys | Fits 2007-2013 Touring FLH/FLT, 2007-2011 Dyna FXD, 2007-2010 Softail FXST/FLST, 2007-2013 Sportster XL by Billy Berry

REF:2010 Harley FLHTCU Ultra Classic, 46000 miles. I am very happy with the results of the Fuelpak FP3. It really woke up the engine with the usual first stage upgrade. I ran 3 autotune sessions, applied each for the first 2 runs and finished on the 3rd. I then uploaded the map to V&H for review. They modified the map and I downloaded it onto the bike. They also suggested I set the gas progression to Aggressive, which I did. I've only driven 300 miles since the last map flash and it pulls like a train and gets better and better each time. Last tank check was 44 mpg. I would definitely buy this again. If you are purchasing this please read the instructions. Please note that it works VERY poorly in autotune mode as it disables some ECM functions in autotune mode (this is documented). Also note that the adaptive fuel adjustment resets every time you flash the map. After flashing the map, it may take up to 2 tanks of fuel to recalibrate the adaptive fuel trim. The only downside in my opinion was the price. This tuner is linked to your bike via its chassis number. You cannot disable this and set up another Harley. However, you can read diagnostic codes from another Harley with the same interface. The FP3 is very expensive, but when you factor in the support and the number of options it can set up, it's really great value. As I said, I would definitely buy it again.
