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. Review: Works good! - Works well on the 2016 GMC Sierra 1500 I just bought. Keeps the truck in V8 mode at all times. It definitely improves the truck’s performance. I haven’t owned the device long enough to know if it drains the battery if left plugged in, but I’m also not leaving it in overnight to learn either. ## Features - Brand New Range Technology AFM/DFM Disabler, Red, Compatible with V6 & V8 GM Motors, Produced by Holley Performance Products (Part #RA003R) - The Range AFM/DFM Disabler allows your V6 or V8 GM vehicle to run in full cylinder mode at all times, preventing the Active or Dynamic Fuel Management system from dropping cylinders.
