Transform your Harley Davidson Heritage Softail Classic FLSTC to how it should have been delivered from the factory with the BoosterPlug fuel injection tuning mod.
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.
We designed the BoosterPlug to be easy and fast to install, so it comes with the correct connectors to let you install it without cutting and splicing wires. No further modifications required.
The smarter tuning choice to optimize the fuel Injection on your motorcycle:
- Soft and smooth throttle response
- Quicker acceleration
- Eliminate the low speed surge problem
- Takeoff made easy by the stronger idle
- Far less popping in the exhaust on deceleration
This version of the BoosterPlug tuning mod covers all versions of the Harley Davidson Heritage Softail Classic FLSTC from 2007 to 2015.
