Looking to upgrade your existing ZFG Racing Standard Tune to a DMS™ Calibration? You're in the right place!
Each purchase of this item is valid for converting one single-goal, standard tune to a DMS™ Calibration.
ZFG Racing DMS™ (Drive Mode Specific) Calibration is our proprietary calibration system that allows each factory drive mode to have its own unique calibration strategy—within a single, unified calibration package.
Unlike traditional across‑the‑board tuning, DMS™ enables ZFG Racing to tailor performance, drivability, and vehicle behavior independently across multiple drive modes, based on your vehicle, fuel type, and intended use.
How to get your upgrade:
- After purchase, please submit a Tune Request (for Modify Existing or Additional Tune).
- Select "YES" when asked if the request is for a DMS™ tune.
- Note: Syncing/reading new files is not required for this request - we will review and modify your existingcompleted tune(s).
- You'll receive an email with data logging instructions once your DMS™ tune is ready to apply.
Configuring your DMS™ Calibration System
Drive‑mode‑specific behavior is configured after purchase, in the Tune Request.
For all DMS™ Calibrations, any Tow‑specific calibration is assigned exclusively to Tow Mode.
IMPORTANT: DMS tunes require use of the TDN App. In some cases, a device upgrade may be required. To verify that your tuning device is TDN-compatible, please see our FAQ: What if I already have an HP Tuners Device?
Custom tuning files and services are non-refundable and non-transferable! You may not use your custom tuning file on any other vehicle or transfer our service, used or unused, to any other customer.
