Easy to install as directed. Wish I could kill a selected code from memory and its operation. I hate EGR valves! Gave some more power and shifts feel little bit firmer. I also removed the throttle baffle cup on the throttle blade.

Hypertech Speedometer Calibrator Reviews

Worked after trying different tire heights

Reviewed By Matthew E (RENO, NV) Reviewed for a 2016 Dodge Ram —10/25/2016 8:13 AM

So it works great, but required trying different tire heights to get it right. First I compared speeds using my hand held GPS unit and it was off after entering the manufacturer spec of my tire. I learned this is not the height I should use, but rather the height of the tire measured from the ground to top of tire with weight of the vehicle on it. My tire according to the manufacturer measures 33.98", however with the weight of the truck on it, it actually measures just under 33".
