Overview

Final calibration details are handled through The Tune Shop's remote-tuning process.

What Customers Are Saying

“The biggest difference is how much smoother and more responsive the truck feels in normal driving.”
“I wanted something that behaved well while towing and still felt strong unloaded. The calibration feels very well rounded.”
“The one-on-one support made the process easy, and the truck drives the way I wanted it to.”

Why Choose The Tune Shop?

The Tune Shop is built around personalized, one-on-one service rather than a one-size-fits-all file. We work with you to understand how the vehicle is used, the modifications it has, and the drivability you expect. Our calibrations are developed with real street use in mind and are intended to deliver smooth, predictable performance across daily driving, towing, highway use, and spirited driving while keeping the calibration matched to the vehicle's actual setup.

SOTF / Switchable Tuning

SOTF / Switchable Tuning is available as a tuning-level variant on this product. This application uses EFILive CSP5 or HP Tuners native SOTF (CMF / CM2450B).

SOTF / Switchable Tuning provides multiple calibrations that can be selected without reflashing the ECM between supported tune positions. Where five positions are supported, the selectable calibrations follow the same general progression as The Tune Shop's individual Level 1 through Level 5 tunes.

Selectable positions: 5
Supported platform for switchable tuning: EFI Live / HP Tuners
Switching method / hardware: EFILive switching or OEM cruise controls; dedicated CM2450 switch optional and sold separately

Switching hardware, tuning devices, controller services, cables, credits, and licenses are not included in the SOTF tuning-service variant unless explicitly stated and remain separate selections where applicable. “All 5 Power Levels” remains a separate option that supplies the five individual non-switchable tune files.
