Hypertech Speedometer Calibrator

Reviewed By Thomas G (Raymond, WA) Reviewed for a 2007 Chevy C/K 2500 —11/10/2009 5:56 AM

I purchased this device to correct my odometer after the dealer installed oversized tires on a truck I bought from them. The installation was a breeze. My 9 year old daughter could have done this. Now my speedo is right on, (confirmed by GPS) and the shift points are correct. Before I was revving to over 2400 RPM at 65MPH. Now I'm right around 1500 RPM at the same speed. My truck also feels a whole lot peppier and does not struggle when I really get on it. It really responds. I've also gained 1.5 MPG since the install and it keeps getting better. Autoanything provided a great product to help me out. The whole purchase experience was very positive.
