TFI Harley Davidson Products

Harley Davidson motorcycles have long dominated the market for riders getting out on the road and it is no coincidence the large number of aftermarket accessories and performance products available to the end users. Navigating through all the products trying to decide which sounds better can be very time consuming and you will hear a lot of biased comments. We are only going to state some simple facts and if we perk your interest then feel free to contact us with additional questions.
  1. TFI controllers are supported by the manufacturer who has one of the highest rated technical support teams in the business. Online forum community support is offered through HDTalking.com.
  2. High cost controllers are overkill for the vast majority of riders. Would you pay $100 more for a 1 HP gain? In most cases the TFI can already out perform the competition anyways.
  3. 2 year unlimited mileage warranty for manufacturer defects.

Is my bike a Dyna, Softail, Touring, Sportster, or VROD?

What really changes between all the model years?
The main changes between the year ranges which creates such an extensive list of part numbers is the injector connector type to plug-in and also the implementation of O2 sensors to the bikes. The Sportster and VROD models also have different base maps because of different RPM rev limits.
