My truck is a 2001 Chevy Silverado 1/2 ton 4 wheel drive extended cab with an automatic and 146000 miles on it. Prior to installation of the Hypertech I could only tow our 4000 lb travel trailer 55mph and it felt strained and going up grades was slow and labored. After an easy install, I can now tow on the level at 60mph with cruise control on. Going up grades is still 55mph but so much less labored and it feels as if the engine is not strained. My gas mileage, observed over several tankfulls, has gone from 10mpg towing to 13mpg over the same roads. The install also needed an internet upgrade that was easy, quick and thorough. I would highly recommend Hypertech.
