Harley Davidson Sport Glide FLSB (2018 - 2020)

Improving the fuel injection on your Harley Davidson Sport Glide FLSB is easy and efficient with the proven BoosterPlug tuning modification.

Compared to the Power Commander, the BoosterPlug tuning method offers similar or better results for must owners - at a much lower price and without the complicated setup.

The BoosterPlug modification requires no programming or advanced mechanical work, and it's easy and fast to install. Plug and play.

Release the full potential in your motorcycle:

- Fix the snatchy throttle response problem
- Improved 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 modification covers all versions of the Harley Davidson Sport Glide FLSB 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.
