Frequently asked questions

What is a Twin Tuner? A fuel injection controller that adjusts fuelling on the stock Harley ECM, ideal after cam, exhaust or air cleaner upgrades.

Do I need a fuel controller after an exhaust swap? Usually yes on fuel injected Harleys: a freer flowing exhaust leans the mixture, and a controller restores proper fuelling.

Do you offer free shipping in Canada? Yes, on orders over $279.99.
