"Wanted to see if I could get a little more power and better fuel economy from a programmer. I previously added a K&N intake and Magnaflow exhaust before adding this programmer to my truck. Speedometer correction is very precise. Added 3 horspower and 3 lbs torque using premium program according to the dyno. No more hesitation when I step on the gas. Gas mileage is a little better, but my driving is very random, both highway and in town, so i can't give exact numbers. Not sure what the numbers would have looked like if my truck was all stock. All in all, I'd say i like it just for the ability to change my speedometer for different size tires and the ability to read DTCs. The extra miles per gallon will eventually pay for the unit, and then save me money." —Ralph C from Oak Harbor, WA bought a Hypertech Max Energy Programmer for a 2011 Chevy Silverado.
