2011 Yukon Denali XL 6.2 AWD
Feels solid. LEDs are semi bright but not distracting. Some people had issues with draining battery power if left plugged in. I drive my truck everyday no battery draining. Itâs always in. Even if Iâm off and it sits for a day or two. Still starts. AFM DOD is not active. Doesnât fix my lifters but itâs preventing further damage. Cheap hack. You get 5 stars

Works as it should for less than Range
This made my 2018 Silverado 5.3 V8 actually a V8! Buy it and donât worry or wait. If you have looked at them just get it. Its awesome when you press that pedal and thereâs no lag from 4cyl to v8 and no awkward shifting back and fourth. That alone is worth the money if there was no mpg saving but there is. I get 1-4 mpg better depending how I drive and even saw 6 mpg better on one trip I made.This works as it should and was very easy to install in the truck. I did put it in a few weeks before a big trip I was taking to make sure it didnât mess with the motor and throw a code but Iâve never had a issue. I do get better mileage now that my truck isnât searching for 4cyl to save gas for 2 seconds then have a 5 second delay to give me my V8 power back. I do notice my truck seems to shift later when I take off from a stop sign and give it a bit especially if Iâm pulling my boat when it didnât do that before. The only thing I worry about is Iâve noticed my truck when idling in a drive through after driving for a bit it seems like itâs running not rough but not quite right and feels like itâs going to idle too low and shut off. It never has shut off but it does still give me a bit of anxiety when I see it happen each time. Overall I would recommend buying this it works great and for half the price of the Range brand. One thing that actually bugs me but itâs because Iâm weird but there are 4 lights on this and I canât figure out why some times 3 are blue when others it will but just 1 Iâve never see all 4 light up at the same time. Again dumb things like that kinda get to me but In no way does it effect the product 100% recommendation.

3 years. Flawless
Shuts off stupid eco mode. No lag on acceleration or clinking like so many vehicle owners experience.
