The Sport Tune includes more than 100 calibration changes from stock, crafted to safely push the limits without risking your truck’s health. The included EFI Live SPADE AutoCal V3 makes flashing simple and secure, and also doubles as a diagnostic tool when you need to scan or log data.

Supporting modifications are recommended for long-term reliability, especially if this tune will be used frequently. For trucks with larger tires or modified transmissions, optional TCM tuning helps keep everything running smooth and in the right rev range. This tune is smart where it counts and aggressive where it matters, giving you controlled performance in a proven, emissions-friendly package.
