Fuel Injection improvements on the Harley Davidson Electra Glide Ultra Classic FLHTCU are usually expensive and complicated. The BoosterPlug is a better and proven alternative.
With the BoosterPlug you will have a better solution than the complicated and expensive Power Commander that is almost impossible to set up correctly.
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
- Stronger idle - no more stalling problems
- Little to no popping in your aftermarket exhaust
This version of the BoosterPlug covers all versions of the Harley Davidson Electra Glide Ultra Classic FLHTCU with the Milwaukee 8 engine (2017 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
