Great towing improvement

I really needed improvement in my Chevy Surburban while towing my 30 ft travel trailer. My vehicle was very slow in gaining speed and maintaining speed on the highway. After reading about the promise about tuners, I decided to give the Hypertech a chance. WOW! What a difference. The improvement in shifting was worth the price!! Very easy to install. I still only get 10 mpg, but at least I am towing with power. I would really like to find a mileage improvement product, but it is a 5.7l.
