Tuning Goals
When you choose a tuning goal, you're also choosing your Tune Style
Single Tuning Goal: Applies the same goal across all drive modes. Each mode keeps its stock personality — Sport Mode remains the most responsive, Eco Mode stays the most relaxed — with refinements based on your chosen goal.
DMS (Drive Mode Specific): Not available for this platform.
Lets you assign different tuning goals to each drive mode, creating varied power delivery and driving characteristics at the turn of a dial. For this tune type, you’ll select goals for each mode after purchase.
Engine (ECM) and Transmission (TCM):
Custom tunes are written to calibrate your Engine & Transmission in harmony with your selected tuning goal(s), modifications, and preferences.

Important Notes:
E85 Tunes - Please read the "Fuel Type" section carefully
Your device will not arrive with a pre-loaded tune. ZFG Custom Tunes require a series of revisions and data logs before completion.
After purchase, please follow instructions for getting started in the "Next Steps" email. These instructions are also found in our Quick Start Guide.
Most tunes are completed within two weeks of submitting your Stock Calibration and first tune request.
Tune requests must be submitted on our website (See:Tuning Central). These requests are required - we will not send a tune, review a data log, or take any other action on your tune until the proper request has been submitted.
Custom tuning files and services are non-refundable and non-transferable! Tunes are vehicle-specific and cannot be reused or reassigned.
