What owners report
We haven't analyzed enough owner reviews for this one yet. Across all plug-in disablers, the usual complaints are warning lights, a flat battery after days parked, harsher shifts on some trucks and a 0–3 mpg drop on the highway.
Who it's for
Best suited to owners of 2007–2021 GM trucks and SUVs with AFM, and pre-2022 DFM trucks with a 6- or 8-speed.
Not for
- 2022.5–2026 trucks and 2021+ SUVs (Global B): it won't work
- 10-speed automatics (2019–2022.0 L87/L84, 2018–2020 6.2L SUVs)
- Corvette C8 and heavy-duty 2500/3500 trucks
- California-registered vehicles
Limits & caveats
- It reduces how often cylinders switch off. No study shows it prevents lifter failure. What fails and why
- if the vehicle will sit a week or more, unplug it.
- Expect 0 to 3 mpg less, mostly on the highway.
- No CARB Executive Order: not legal on California-registered vehicles. OBD-based inspections elsewhere may also flag it.
