Harley Davidson Tuners

We have a vast range of Fuel Injection Management Modules, ECM & EFI Tuners available to order for Harley Davidson motorcycles.  Your Harley Davidson ECM comes perfectly setup for managing the fuel delivery when no changes have been made to the bike i.e. your Harley still has all the original stock parts attached to the motor. But if you replace the stock exhaust on your Harley or you increase the air flow to your motor with an aftermarket air filter then you should really look into buying a fuel management module that can be used to alter the mapping on the ECM so that the fuel is managed correctly. After all, if you have spent the money on improving the exhaust system or air flow you may as well get the most out of it! We have a number of different options for you to choose from so take a good look as some have much more to offer than others.  If you need any advice, feel free to email us with your questions or you can give us a call.
