Review on 🏎️ Enhance Speed Accuracy with Rough Country Speedometer Calibrator for 2018-2020 Ram 1500 Truck - 90019 by Maurice Jimenez

I bought it on my Ram 1500 5.7l 2019. First of all, the installation instructions said update first, that was the first problem. When you go to a website and click refresh, malicious Bytes and Windows Defender block the download. They think it is a teal backdoor Trojan, which is scary to say the least. I had to turn it off for both installing on the PC and updating the tool. I emailed rude country and got no response. I took a chance and built and mounted 33.5" tires to 285/60/20 specs. My speedo was off by 2 or 3 mph in the opposite direction so I settled on 33 inch tires. Still 1 mph at 60 and 2 mph at 80 mph. On traction control I'm not sure as the tire size is wrong at the moment. I don't want to get smaller. As others have said, the tire size isn't accurate, leading me to believe that traction and stability control are disabled.
