Hypertech Speedometer Calibrator

Calibrator That Works

I read many reviews on this calibrator before my purchase. I decided to buy and install the Hypertech Speedometer Calibrator. I programmed the unit for my particular vehicle, a Toyota Tundra with 35" tires. Since the installation, my truck no longer surges while in first gear, maintains consistent rpm's on the highway, and performs better than prior to the installation. Minimal fuel mileage improvements, but worth the purchase. View more reviews...

Superchips FlashCal F5 Calibration Tool

F5 flashcal

I purchased the flashcal f5 for my 2011 f150. I used it to recalibrate the speedometer on my truck. It is a great product and I really recommend it. Changing the gear ratio to match the tire size was great. View more reviews...
