Review on 🚀 Hypertech Speedometer Calibrator for 2007-2019 GM Trucks & SUVs; 2006-2016 GM Diesel & 2006-2015 GM Passenger Cars by Mike Calderon

Don't listen to negative reviews, they have no idea what they are talking about. A few years ago I dropped the stock tire size to 33 which didn't make much of a difference and I haven't noticed much of a change. About a week ago I said why not and bought 35 inch tires. I started driving around. I suddenly noticed that in order to maintain speed on the freeway, my engine had to work harder (higher revs), the shifting wasn't smooth, and something suddenly or suddenly was wrong with the car. I did a little research and came across this one. When you get this, the first thing you have to do is go to your computer, plug it in, go to the website and download the app. Once installed, click any make and model of your car and it will update automatically. to see how much they charge me and they wanted to steal $300. Pure greedy theft. I would pay $50 for a store to do this, not $300. Buy this thing and keep it, I know it only has one purpose, but if you're planning on changing the battery and keeping your car, that means unplugging the negative cable for more than 10 seconds and I'm pretty sure sure it will reset your system and you will have to use it again. My car is a 2011 Suburban 1500 4x4.
