Features, Description, Q&A, Specs & Installation
Corrects Speedometer / Odometer. If you have installed a set of tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, Hypertech’s Speedometer Calibrator allows you to correct your speedometer and odometer readings. The vehicle’s computer calculates your speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is actually going. As a result, the speedometer/odometer readings will not be accurate.
Diagnostics Tool. The Hypertech Speedometer Calibrator can also be used as a diagnostic code reader. Save yourself time and money by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.
Easy to Load; Easy to Restore. When you make changes to your vehicle, the Speedometer Calibrator automatically stores your vehicle's factory settings. To return to the original factory settings, just plug the Calibrator back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work. Once you have the vehicle back from the dealership, reinstall the Speedometer calibration as before. Please note that the Speedometer Calibrator can only be used on one (1) vehicle at a time.
Internet Updateable. The Hypertech Speedometer Calibrator comes with a USB cable and a CD containing software to enable quick updates over the internet. If your vehicle has a new calibration not available when your Hypertech Speedometer Calibrator was manufactured, it is possible that you will see a “Cal not found” message on the screen. If this occurs, you can simply update your Speedometer Calibrator with the correct new calibration via the internet. Simply connect the Speedometer Calibrator (using the provided USB cord) to your computer and go to www.hypertech.com. Then click on the Support button to get update downloads.
Application. This Hypertech Speedometer Calibrator is designed to fit 2006-2017 5.7L, 6.4L RAM 3500 models.

Words as advertised
As people have said before me. Slight increase in miles per gallon, but that’s enough to worry about and is very consistent now I am getting about 21mpg add a steady 75mph on the highway in about 18 in the city without the device, I was ranging overall about 20mpg. The thing I’ve noticed most by the seat of the pants my Silverado seems to accelerate a bit better than before could be me. I’m not sure.

Looking for engine protection via Hypertech PowerStay
This product appears to be working. The price was better than the other brand I also purchased here(more expensive). They both seem to be doing their job as far as the display says (no V4 light). All of these AFM suspend units I've tried tend to make the truck drive a little different, not bad, just different, noticed in the shifting. I hope this unit will learn or I will and the truck will be as should have been.

Tow tuner
Very nice product, easy install, put 1200 miles on my truck pulling a large camper,was very impressed with the difference between stock and tuner, helps the truck shift when it should! Don’t care what anyone else thinks,this tuner works well! Recommend this tuner to anyone pulling heavy loads
