Harley Tuners for Stage 1 and Up

Bolt on an air cleaner and pipes, and the factory fuel map is wrong. A tuner fixes it so the bike runs cooler and pulls the way it should. We stock tuners from Dynojet, Vance & Hines, Thundermax and Fi2000.

  • Flash tuners: Dynojet Power Vision 3 and 4, Vance & Hines Fuelpak FP4
  • Piggyback: Dynojet Power Commander 5 and 6, with auto tune kits
  • Replacement ECMs: Thundermax with integral autotune
  • Cables and accessories: Power Vision interface and diagnostic cables

Tuners are listed by year and model, so check the fitment for your ECM. Do it with the rest of the Stage 1: air cleaners and exhaust. Running a Sportster? See Sportster tuners.

Not Sure It Fits?

Year, model and ECM all matter. If you can't tell whether something fits your bike, hit us up with your year and model and we'll check it before you order.
