Do you really need a Dyno tune?
First of all, the term "Dyno," is just short for "dynamometer" which is a way for performance shops to simulate vehicle operation without having to be driving on the street. This allows technicians to control engine speed and load while monitoring conditions on the motorcycle such as air/fuel mixture, exhaust gasses, ignition mapping, throttle position, and fuel injector timing. It can be a very useful tool, and is just one resource we use on a daily basis to keep your Harley® running at its best.

Dyno tuning is only necessary if you have done something to the bike that has changed it from its stock powertrain configuration. (Harley-Davidson® calls this RACE USE ONLY in catalogs meaning that the bike isn't street legal anymore.)

  1. The first step of the performance path that people frequently do to their new bike is install mufflers, a high flow air cleaner, and some kind of tuner, which alters the air/fuel mixture and ignition timing to optimize the new exhaust and air intake systems. A frequent question is, "Should this be dyno tuned?" If you are using a Harley-Davidson® Super Tuner and use the appropriate download for the year and model, mufflers, and high flow system, you should be running close to perfect.
  2. Dyno tuning should be done if you have a concern with how the bike runs and performs depending on additional modifications as well as your individual riding style. We have found dyno tuning a bike with mufflers, high flow, and a race tuner changes horsepower and torque very little - only 2 horse power and 2 pounds of torque compared to just running with the factory provided download.
  3. The air fuel ratio is in many ways more important than power and torque; the ideal air fuel ratio should be around 12.7 parts air to 1 part fuel. Maintaining that ratio not only maximizes engine performance, but also allows for best fuel economy as well. Running too rich wastes gas. Running too lean creates excessive heat which contributes to drivability problems and possibly engine damage. The race tuner map allows us to dial in with great precision to maintain that 12.7 to 1 regardless of engine RPM.
  4. Exhaust Systems can mean complete head pipe system or head pipes and slip on mufflers. Should THIS be dyno tuned? Once again the answer is if you are using a Harley-Davidson® Super Tuner and use the appropriate download for the year and model, exhaust system, and high flow set up, you should be running close to perfect. Now on this type of upgrade, there may be more drivability problems than with just mufflers due to the head pipe change. Many customers feel that the bike backfires too much on deceleration or when letting go of the throttle. The dyno MAY fix most of the deceleration backfiring, but typically not all of it. The bike will most likely still have some amount of minor backfiring which should be considered a normal condition for that performance set up. Should you get the bike dyno tuned in this case? It depends. Dyno tuning the bike will often help gain about 4 to 6 horse power and about the same in torque. The air fuel ratio will be close to where it should be with just a download, but it may be a little bit lean. Dyno tuning allows us to get that critical air fuel ratio back where it needs to be. Deceleration adjustments can be made at the same time and will help with any backfiring issues.
