Level 5: +165 HP

The highest standard power level included in the regular tune lineup.

This aggressive calibration is intended for maximum-performance applications and may exceed the long-term capabilities of factory engine, transmission and driveline components.

It is not recommended for towing.

SOTF — Switch on the Fly

Switch-on-the-fly tuning may be available for compatible trucks.

SOTF allows the driver to change between multiple power levels without reflashing the ECM each time.

SOTF Switch Required

A compatible physical SOTF switch must be installed to use the switchable tune file.

The SOTF switch is not included with this tune-only product unless separately purchased.

Without a switch, you will use individual power-level files and reflash the truck whenever you want to change levels.

TCM Transmission Tuning

Optional TCM tuning is available for supported:
2020–2025 Ford 6.7L Powerstroke trucks only.

TCM tuning is not currently offered for the 2026 application.

Transmission tuning may improve:

• Shift scheduling

• Shift firmness

• Torque-converter lockup strategy

• Power delivery between shifts

• Overall drivability with higher-output engine tuning

TCM availability depends on the truck’s year, transmission, module operating system and calibration support.

Available Specialty Tune Options

The following options may be available depending on the truck’s ECM operating system:

LBF

LBF may be available on most supported operating systems but is not guaranteed for every truck.

Hiss

Hiss-style idle or exhaust-sound calibration may be available on most supported operating systems.

Rumble

Rumble tuning may be available for compatible operating systems and vehicle configurations.

Limiter

Limiter-style tuning may be available for supported trucks.

Availability of LBF, Hiss, Rumble and Limiter files is confirmed only after the truck’s VIN and operating system have been reviewed. Some options may not be compatible with certain model years, software versions or truck configurations.

EZ LYNK Linking Process

Your EZ LYNK support package is pre-linked to the correct Sasquatch Diesels technician using the VIN provided with your order.

You do not need to manually enter or add a technician email address.

After connecting your AutoAgent and opening the EZ LYNK app, the correct technician invitation will appear for you to accept.

Make sure the VIN and EZ LYNK account email entered at checkout are accurate. Incorrect information may delay delivery of your tune files.

Flashing Requirements

Before flashing:

• Connect a regulated battery charger to the truck

• Confirm that both batteries are fully charged and in good condition

• Keep your phone or tablet close to the EZ LYNK AutoAgent

• Keep the EZ LYNK app open throughout the flash

• Do not open doors, press the brake pedal or operate accessories

• Do not unplug the AutoAgent

• Follow every key-cycle instruction exactly

Low or unstable voltage may interrupt programming and cause communication, flash or module-recovery issues.

FORScan and Ford IDS Warning

Any previous changes made through FORScan, Ford IDS or another Ford programming platform should be returned to the original OEM values before flashing Sasquatch Diesels tuning.

Non-factory module settings may interfere with the calibration or cause warning messages, communication problems and unexpected vehicle operation.

Dealership Warning: Do Not Flash the Truck

When taking the truck to a Ford dealership or repair facility, clearly instruct the service advisor:

“DO NOT FLASH OR REPROGRAM THE TRUCK.”

A dealership software update may overwrite the custom calibration or install a software version that is not compatible with the existing tune files.

Additional charges may apply if new files or revisions are required because the truck was reprogrammed by a dealership or third party.
