Do I need a custom tune to use this SOTF switch, and is it legal for street use?
Yes, you need a custom tune from Tuner Depot that is specifically written to support Switch on the Fly functionality. The switch is just a controller; the tunes define the power levels. Regarding legality, it is not legal to use this switch for deleting federally mandated emissions systems (DPF, DEF, EGR) on public roads.
How difficult is the installation process for a DIY mechanic?
Installation is generally straightforward for most DIY enthusiasts. It involves:
- Plugging the switch into a dedicated port on your engine's ECM or a compatible tuner module.
- Routing the wiring harness.
- Mounting the switch on your dash or console.
No advanced programming is required as the pre-loaded custom tunes handle the adjustments. Most installs take under an hour.

Can I use this switch to turn off my DPF/DEF/EGR systems?
The SOTF switch itself does not delete or turn off emissions systems. Its function is to change between power levels programmed into your ECM. It is used to control custom tunes designed for trucks with DPF, DEF, or EGR systems removed. Both the physical delete kits and matching custom tunes are required for those modes to function.
