Money-back guarantee.
Savary is designed to deliver smoother, more consistent performance. If it is not the right fit for your vehicle, reach out and we will help resolve it.
Is this the same as the Savary Scan Tool?
No. The Scan Tool reads diagnostic codes. Savary is positioned here as an AFM/DFM disabler for compatible GM vehicles.
Will this void my warranty?
No flashing or reprogramming is involved. Remove it before service so the vehicle returns to factory behavior.
How hard is it to install?
Installation is simple. Plug it into your OBD-II port, start the vehicle, and drive. No tools are required.
Will I lose gas mileage?
Most owners report little to no noticeable difference in everyday fuel economy. Results depend on vehicle and driving style.
Does it work on newer trucks with DFM?
It is designed for compatible GM V6 and V8 vehicles equipped with AFM or DFM. Check fitment before ordering.
Will it trigger a check engine light?
It is designed to integrate through the OBD-II port without flashing the ECU.
What about emissions testing?
Remove the device before emissions checks or dealer diagnostics, then reconnect it afterward if appropriate.
