2011 Tacoma bdx tuner

Reviewed By Christpher T L (Newport News, VA) Reviewed for a 2011 Toyota Tacoma —1/26/2018 2:33 AM

The bdx tuner made an immediate difference in my vehicle performance. I truck uses less gas, shifts gears smoother, and makes my truck sound amazing. It took about 30 minutes to install and about 10 minutes to change to each program setting. Installing the bdx tuner was the best investment I have made to enhance my trucks performance.

Hypertech Max Energy Programmer Reviews

Great device!

Reviewed By Evan S (SANTA CLARITA, CA) Reviewed for a 2004 Nissan Titan —1/11/2018 10:20 PM

Without changing the rpm limiters, the device changed my cruising rpm to around 900. I took my rev limiter off, and now I go all the way up to the red line when flooring it. I have seen my gas mileage go up. Before, I was averaging around 10.8 with hills, and around 11.2 on flat. Now, I am up to around 11 with hills, but 15 on flat. Its a great device and I would recommend it.
