Bought this as a gift for my husband for his 2016 GMC Sierra. If you don’t have one, GET ONE! He says the power is instant, no lagging anymore and fuel mileage is better!! He didn’t notice a difference in fuel mileage right away but after using it for a few weeks, he said his fuel mileage has never been better! I read some reviews to unplug it as it drains your battery. So far he has never unplugged it and has never had an issue so let’s hope it stays that way. Buy it, you won’t regret it!

2018 gmc Sierra with eassist. If you want something that you plug in and basically forget about, this works like it's supposed to. However it's not perfect. It does turn off the auto stop and the DOD. When slowing down and coming to a stop, the transmission sometimes studders (best word i can describe it). If you don't mind a few extra seconds (without the Range device) put the transmission in L and select the highest gear available. This keeps the auto stop off and it stays in v8 all the time. The truck will drive normally.

I am in Australia. Ordered through Amazon. I read as many reviews I could find. Used in the Chev 1500 Silverado for a week or so and found it to be as advertised. Can't fault it at this time.
