WHY RIDERS CHOOSE IT:

• Pre-programmed with the best settings for your HMF exhaust
• Push-button interface with load-based tuning
• Plug-and-play install with no computer or dyno needed
• Full-range tuning across the RPM band

WHY YOU NEED A TUNE:

An aftermarket exhaust changes how much air your engine moves, so the fuel needs to be retuned to match. HMF requires a tune with its exhausts, and running one without a tune voids the HMF exhaust warranty.
