Hypertech Calibrator keeps it all legal

Reviewed By Ronnie R (Corpus Christi, TX) Reviewed for a 2014 Ford F-150 —8/5/2016 4:53 PM

Purchased this after having my son's truck lifted with 35" tires. We wanted to capture his desire to have the look of a big truck while still maintaining the correct speedometer readings and transmission shift points. The system does require you to use a Windows based PC to update the unit to the most recent software package (it is not Mac compatible), but other than that it is very straight forward to use. Hook it to the OBD port, input your tire size and allow it to update your ECM, that's it.

Worked well!

Reviewed By Shane P (MOORE, OK) Reviewed for a 2015 Chevy Silverado —6/10/2016 4:39 PM

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.

I took me 4 adjustments but it was easy to do and got it dialed right in.
