Hypertech Speedometer Calibrator Reviews


2015 Toyota Tundra 5.7L

Reviewed By SHAWN S (Saint Augustine, FL) Reviewed for a 2015 Toyota Tundra —1/15/2017 6:15 PM

Awesome product!!! Great step by step instructions. Had 0 problems with the installation, it took about 45 minutes from start to finish. I would recommend you measure your tire to get the exact size. I upgraded to a 22in wheel with 35s and programmed 35s first and it was still off 2 MPH. Once I measured and saw that it was really a 34, I programmed that in and it was perfect. Much smoother shifting too. I also noticed a 2mpg gain too!!! This is a must if you have a lift Tundra with 35s or larger

The BDX tuner is awesome you can feel the HP... only disappointment is for my truck you can't change tire size so I have it combined with hypertech speed calibrator to gather they work great though...

The quality of this product is great. Instruction was very easy to follow. Noticed 3 mpg better on the city. I actually got 4 mpg better on the highway. Definitely notice the quicker response on throttle body and definitely noticed the HP gained. Not exactly sure how many HP at the Wheels. Goo products and recommend to buy.
