Fixed SEVERAL issues. - 2013 Silverado 5.3L. I had always noticed a slight stutter in the engine. The check engine light was intermittent. It was consuming oil. And recently, in the mountains, it wasn't shifting smoothly and was lagging. Did some research. All those issues were common to the AFM. I took a chance and got this. Just plug and play. So easy. Immediate smoothing of the engine and better power. In a couple days the check engine light went off and stayed off. The other day, hubby took it off, and said the truck ran so bad he put it right back on. Now he sees it too. He said he didn't see much difference, but he does now that he drove it with it running good. Absolutely recommend.

Fixed SEVERAL issues. *by D***S on May 23, 2025* 2013 Silverado 5.3L. I had always noticed a slight stutter in the engine. The check engine light was intermittent. It was consuming oil. And recently, in the mountains, it wasn't shifting smoothly and was lagging. Did some research. All those issues were common to the AFM. I took a chance and got this. Just plug and play. So easy.

Absolutely recommend. ### ⭐⭐⭐⭐⭐ Easy to install *by B***& on February 25, 2026* Awesome results happen right away! ### ⭐⭐⭐⭐⭐ Fantastic investment for the Chevy 5.3 07-13 *by H***. on December 6, 2025* I have a 2013 Silverado with the 5.3. It has that fuel management system where it cuts off combustion to cylinders when you're in cruising gear at cruising speed.. over time that system will fail. I bought this to bypass that feature. Plugged it into my truck June of 2024 and I have not had a problem since. my system had not failed yet. My check engine light would come on periodically so I would gun the motor up and down the freeway and I saw that problem but it was temporary. Then i bought the Ranger. The Ranger solved it for me permanently AS LONG AS IT IS PLUGGED IN to the vehicle.
