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".

Great little tool

Reviewed By Todd K (Huntley, IL) Reviewed for a 2016 Chevy Silverado —10/25/2016 3:39 AM

It added a noticeable amount of power and helped my gas mileage. There are a lot of options that it lets you change and is pretty easy to use if you have some automotive knowledge
