The Fine Print
What the listing doesn't tell you
But one reviewer noticed lower fuel economy and said the plug didn't feel fully seated.
What reviewers actually say
First, reviewers say it's true plug-and-play, taking less than a minute to plug into the OBD-II port and start working.
Second, many say it keeps their engine running smoothly in full V8 mode, eliminating the jerky cylinder deactivation feel for good.
Questions people ask
- Yes, just unplug it to instantly return to factory settings. What problem does it solve?
- It stops AFM and DFM cylinder deactivation, which can cause vibration and lifter wear over time.
