Improving the fuel injection tuning on your Harley Davidson Low Rider FXLR is easy and efficient with the proven BoosterPlug solution.
Compared to the Power Commander, the BoosterPlug offers similar or better results for must owners - at a much lower price and without the complicated setup.
The BoosterPlug tuning module is installed in less than 10 minutes. It plugs directly into your bikes wire harness using original connectors – no cutting or splicing.
Release the full potential in your motorcycle:
- Improved and softer throttle response
- Harder acceleration
- Say goodbye to the low speed surge issue
- Powerfull idle and no more stalling
- Far less popping in the exhaust on deceleration
This version of the BoosterPlug tuning module covers all versions of the Harley Davidson Low Rider FXLR with the Milwaukee 8 engine (2018 - 2020).
Please note that we can not build a BoosterPlug for the "2021 and newer" model due to new emission regulations. You can see the detailed explanation here
