Harley-Davidson Motorcycle Custom Tune
Pricing being finalized
This configuration's price is being confirmed — contact SDPI to order.
Details
Custom calibration for Harley-Davidson motorcycles — built one machine at a time against your exact model, ECU calibration and mod list, not pulled off a shelf. Supported models, tuning platforms and pricing for Harley-Davidson motorcycles are being finalized. Contact SDPI with your machine's details and we'll confirm your application and your price before you order.
What we'll need from you
- ▸ VIN and ECM operating-system / calibration number
- ▸ Year, make, model, engine and transmission
- ▸ Current modifications and what you want out of the tune
- ▸ Stock/read file upload — required on most platforms (EZ Lynk orders usually don't need one)
After checkout you'll complete a guided questionnaire and secure upload tied to your order. See the tune revision policy.
