Super easy install. The device is tiny but still really easy to read. Tons of information.

Hypertech Speedometer Calibrator

Reviewed By Kevin B K (SAN TAN VALLEY, AZ) Reviewed for a 2011 Toyota Tacoma —5/18/2018 8:23 PM

Real easy to program and install. Took me about 30 minutes to hook up. I left the USB cable attached in velrco behind the access door for fuse box, in case I ever need to adjust in the future when I get gears. Only issue I had is the box attempted to some update with the firmware and would fail. I emailed there support and they said to ignore it. I was still able to calibrate with no problem. CD did not come with my product neither I had to email support to get the link to download the program.
