Fuel Injection improvements on the Harley Davidson Softail Slim FLSL are usually expensive and complicated. The BoosterPlug is a better and proven alternative.

Did you think the complicated Power Commander was the only way to sort out the fuel injection on your bike ? The BoosterPlug will offer the better solution at a fraction of the cost.

No complicated mechanical work or programming is required when installing the BoosterPlug. You simply plug it in using the original connectors and you are done.

There is no better way to improve your riding experience:
- Eliminate the poor on/off like throttle action
- Stronger acceleration
- Remove the low speed surging
- Stronger idle - no more stalling problems
- Minimize the backfire in your aftermarket exhaust

This version of the BoosterPlug covers all versions of the Harley Davidson Softail Slim FLSL with the Milwaukee 8 engine (2018 to 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.
