Is a Fuel Tuner really necessary?

Not all machines require tuning and we’ll tell you if it is needed or not.  With modern fuel injection systems, they do not typically have the capability to compensate for the increased demand for fuel when an HMF exhaust is installed. 

We test and tune all the machines we offer exhausts for. That way, we can verify if a machine will run with a safe air-fuel ratio without a tuner. If a machine runs lean during our testing, we explore tuning options and try to develop easy solutions to fuel tuning to complement our exhaust.

How do I know if my machine needs tuning?

Every exhaust system on our website is marked for tuning.  Read the tuning description for your machine to determine whether we recommend fuel tuning or not.  If your machine is marked "Fuel Tuning Required", then your machine must be tuned with an HMF exhaust system.  Failure to tune the engine can cause excessive damage to the exhaust system and engine while voiding the warranty on your exhaust and possibly on your machine.

Is a Fuel Tuner really necessary?

If your machine is marked "Fuel Tuning is Not Typically Required", then fuel tuning is not required when installing an HMF Exhaust on this machine. However, other modifications to the machine may require the need for fuel tuning to ensure the machine runs properly, and there is no damage to the exhaust system.
