Great product

Reviewed By mike t (CONCORD, CA) Reviewed for a 2011 Nissan Frontier —3/28/2017 7:08 PM

Had a hypertech programmer for my Silverado years ago and thought I would try it on my Nissan pro4x Frontier v6 with a six speed manual. I have it tuned just at 87 octane. Definitely feel the difference. Also gained a 1-2 mpg more.

Installed larger tires on my 2010 Toyota Tundra after doing so traction control was off badly when acelerating at speed it would imeditly kick in. After installing all is correct now and I'm getting 1.5 mpg better on gas mileage. 5 stars
