2017-2019 F250-F550 CAB AND CHASSIS Tuning Package (ezlynk)

Engine and transmission tuning package for 2017–2019 Ford F-250 through F-550 Cab and Chassis platforms carrying the 6.7L Power Stroke. Calibrated specifically for the C&C factory PCM baseline — not the same as the pickup tune.

What's included

• Custom VIN-locked ECM calibration built around the Cab and Chassis factory programming and load-carrying demands
• 6R140 TCM calibration with shift pressure, scheduling, and converter strategy suited to upfitted chassis work
• Switchable power levels via ezlynk AutoAgent 3 app
• Datalogging support for EGTs, boost, fuel rail pressure, and transmission temps

How it works

Files are pushed wirelessly to your ezlynk AutoAgent 3 device and flashed over OBD-II. Requires an ezlynk AutoAgent 3. Order this C&C-specific package — do not use the standard pickup tune on a chassis cab.

Support tiers

• Limited — 4 Weeks: Revisions available for four weeks post-purchase; tune remains on the device permanently.
• 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.
