Dyno Tuning is currently not available

due to the Covid -19

Dyno Tuning, sometimes known as dyno testing or mapping, is essential to realizing the full potential of today's fuel injected and carbureted  motorcycles with performance modifications.

The only way to accurately calibrate fuel and ignition maps while diagnosing run and drivability issues in a controlled environment is to dyno test your motorcycle. 

At Star Power, we have technicians who are trained to map TTS Tuners, for your Harley®.

A baseline dyno run will provide you torque, horsepower, RPM and AFR measurements. 

Tuning will also properly diagnose and correct fuel or ignition problems, optimize your motorcycle's performance and measure the affects of changes or modifications.

Dyno maps or graphs will be printed for a before and after comparison.

Our Current rate for Tuning is $500. You will need a TTS Tuner or S/E Tuner.

TTS Tuners are available for purchase at our Shop for $440.

Most mapping can be done in four hours or less, but varies based on the number of tuning variables and how the bike responds to tuning changes.

Additional labor cost may be incurred if parts installation is required.

You will need the larger O2 sensor ports. Not all exhaust come with the larger ones.

Smaller one is stock.

Dyno Tuning at the Star Racing facility (123 Crisp Drive, Americus, Georgia) must be scheduled in advance.
