First of all I was impressed with how quick it arrived, the experience in using it!I after installing it and driving it I was totally impressed with the acceleration especially from 20 mph onward, the truck acted like it had a blower on it, and when I hooked up my toyhauler which was the main reason for getting the chip, I was very impressed by how it seemed like my truck doesn't have to work as hard pulling,didn't help mileage empty or pulling I have 01 GMC 6.0 200600

works great

Reviewed By William W (COLUMBUS, OH) Reviewed for a 2014 Chevy Silverado —6/27/2015 12:06 PM

I initially set the unit for 34" tires, the diameter of my Toyo ATIIs in 295 60r20, the speedometer was actually a couple mph over. After some downward-tweaking for tire inflation level, I setting the unit to correct for 32.75 inch tires got my speedometer accurate to within less than 0.5mph error compared to Garmin GPS. Keep in mind that actual tire diameter is dependent on how many psi you are running, so getting things right on the money may take some tweaking.
