Improving the fuel injection on your Harley Davidson Sport Glide FLSB 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 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 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
