Husband hated it. Said his truck ran better without it.

Plug and Play
I used this on a 2007 Suburban with a V8 automatic trans. I just plugged it in, and it workedâno muss, no fuss. Otherwise, the seller advises unplugging the device when it is not in use to avoid battery drain.

Didn’t do what I got it for
I have a manual transmission, and when I’m in traffic or sit through a light, it will do a “gears skipped for fuel economy” thing and lock out the transmission forcing you to shift from 1 to 4. There is a couple things that will get around it – either run first gear out to a higher RPM, or shift to neutral and wait .5-1 second for the message to clear, both of which are mildly annoying. I got this hoping it would override that one line of code, and unfortunately, it doesn’t. I drive my car in performance mode, which changes several driving characteristics, so this device didn’t change my car at all. For reference, 2017 Chevy SS.
