Why re-tune your bike?

Your bike comes from the factory tuned to have a certain amount of fuel and air going into the engine, and a certain amount of spent fuel and air (exhaust) leaving the engine. When you increase the exhaust flow by using a less restrictive muffler and header system, you create that big, deep Harley sound we all love, and better performance. But you also alter the rate of exhaust flow that your bike was tuned to. This causes the bike to become out of tune. And typically run lean, which is to say hot. The same is true when you upgrade to a high performance air filter, as it lets more air into the engine, causing the engine to become out of tune.

By adding a Dynojet Power Commander V with a pre-installed map for your bike, you instantly, and easily readjust the air / fuel ratio bringing it back into tune for more performance, better fuel economy, and longer life.
