I purchased the Hypertech Max Energy E-Con programmer strictly to improve fuel economy. Installation was simple. After 500+ miles of driving ( 90% highway, ave. 70 mph )my fuel mileage increased 1 mpg. I am in the process of adding a cold air manifold system, and a cat back exhaust system. My hope is to increase overall mileage 3 to 4 miles per gallon.
