20-22 F250-F450 6.7 PSD Engine Tuning (ezlynk)

Engine-only tuning for the 2020–2022 Ford F-250 through F-450 6.7L Power Stroke, delivered via ezlynk AutoAgent 3. The fourth-gen 6.7 features a new high-pressure fuel system and revised turbo architecture — this calibration is engineered specifically for that hardware.

What's included

• Custom VIN-locked ECM calibration with five switchable power levels: 0, 30, 60, 90, and 135 hp over stock
• Optimized fueling, injection timing, and boost targets at each power level
• ezlynk datalogging for boost pressure, rail pressure, EGTs, and fuel trims

How it works

Tune files are delivered wirelessly to your ezlynk AutoAgent 3. Plug the device into the OBD-II port, sync via Wi-Fi, and flash. Switch between all five power levels on demand from the AutoAgent mobile app. Files are VIN-locked to your specific truck.

Support tiers

• Limited — 4 Weeks: Four weeks of post-purchase revisions; the tune stays on the tool permanently after that period.
• Full — Lifetime: Unlimited revisions for the life of your ownership.

All calibrations are developed for emissions-compliant performance and must be used in accordance with applicable local, state, and federal regulations.
