Great Improvement!
Works great! Plug and play. No loss of mileage, in fact, I picked up a 5% improvement with the truck not dropping to four cylinder then reacting and downshifting to catch up.Highly recommended!

Works well.
Installed on a 2018 Silverado about a week ago. V-8 is now always on, no more 4 cylinder drone. So far the auto shut off is also off. What a difference. Two of Chevrolet's annoying crud gone. I am pleased. GM - are you listening?

Works good.
Works good, but it runs the battery down if you leave it plugged in.

Shocked
I always thought it was a gimmick but it actually does allow it to stay in v8 mode , idle is by far smoother and it sounds by far better, if you have afm/dod spend the 40 dollars and no it doesn't drain your battery mind es been in 2 days and no issues. It's truly plug and play.

Worked well for a few months
This is an expensive band aid. It helped with my car and just recently failed, which now led to me having to fix the V8/V4 switch anyway. So good product if you can’t afford the major repair right away, but this will fail after a few months.
