The BoosterPlug is the easiest and most efficient way to sort out the common fuel injection problems on your Harley Davidson Street Glide Special FLHXS .

Optimizing the fuel injection on your bike does no longer require expensive and problematic devices like a Power Commander - and no time consuming setup procedures.

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.

A true plug and play solution that will make your bike so much better:
- Fix the snatchy throttle response problem
- Stronger acceleration
- No more low speed surging problems
- Stronger idle and less tendency to stall
- Deceleration backfires in the exhaust reduced to a minimum

This version of the BoosterPlug covers all versions of the Harley Davidson Street Glide Special FLHXS with the Milwaukee 8 engine (2017 to 2020).
If you have an older Street Glide Special FLHXS, you can find the BoosterPlug tuning module for it in the related products below.

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.
