Review on 🏎️ Hypertech 730123 Speedometer Calibrator: Accurately Calibrate with Ease by David Olson

I have 33" tires on my 2016 Tacoma V6 4x4. The truck didn't feel sluggish with the tires, but the speedo was 10% slower than mine (less than my actual speed). Shift points should be off and fuel consumption fluctuate. After installation there was a noticeable difference in handling and it now feels 100% smoother and at the right time shifting and gas mileage has increased. I get 19mpg. Medium with 33 and non-original bumper (non-aerodynamic)
