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.
