You've fitted a new air filter & exhaust system to your motorcycle, but suddenly it doesn't behave and run smoothly anymore. The original calibration doesn't help, the exhaust is backfiring and the engine temperature is abnormally hot.
The Don Tuner by Don Performance offers bespoke engine tuning maps for Harley-Davidson motorcycles that have been modified with OEM or aftermarket components such as air filters, exhaust systems or camshafts, and can also improve unaltered motorcycles from the factory.
This software optimises the power, torque and engine running of your Harley-Davidson to protect against overheating due to lean running, and can be used with selected Softail and Touring models.
Softail Models | 2016 - 2024 |
Touring Models | 2008 - 2024 |

Other benefits include smooth engine operation and reduced engine temperatures during idle or while riding.
The Don Tuner works with any combination of air filter, exhaust system or camshaft profile, and provides a bespoke engine tuning/mapping for your Harley-Davidson.
