Review: My truck is a 2017 gmc sierra 1500 with a 6.2motor, 8 speed trans. It has been a night and difference for the better. Better fuel mileage, smoother shifts, more power at any given moment. My truck is a beast let out of its cage, or the perfect work horse pulling away. I have had this in my truck for three months. No shaking or hesitant shifts, just a very happy truck. Worth every penny. Just buy and thank me later.

### ⭐⭐⭐⭐⭐ Review
*by B***H on 26 December 2025*

This device is instant. I love it. I own a 2010 Chevorlet Avalanche LT. I never knew nothing about this technology. My retired Coworker told me about it actually at a funeral. I ordered it. I called him and gave him the biggest thanks. The range is litterally saving my engine from ruin. Every time the Avtive Fuel management system kicks in I hear the lifters and pistons knocking and rocking. Thats a scary sound to me because that engine is under load doing that. The range device stopped all of that. My old V8 vortex engine is a happy girl now. Im loving the full time power especially when im climbing up 280 westbound here in New Jersey. We got some serious hills here and they are murder on transmissions and engines. I dont even care about the fuel mileage because I do drive local and local driving tears your car up anyway on the feul side. My truck runs so smooth now I dont have to play with the gas pedal anymore fearing that im damaging the engine. Now I drive with more confidence. Going up hills is smoother and I can actually keep up with traffic. The Avalanche was never speed pourpose built but now she moves. I took it other highway for a 40 minute drive yesterday to go somewhere usually I be in the right lane letting everyone go past me at speed but now I keep up with traffic. Its definately worth the money. All you do is litterally plug it in let it work its magic for a couple of litteral seconds and drive. It does not have any negative impact to your vehicle at all. Im so happy now.
