"I think that the hypertech max energy was easy to install it looks great and the power is amazing. I will definitely recommend it to my friends." —William P from Ranger, GA bought a Hypertech Max Energy Programmer for a 2003 Ford F-350.
"Have noticed significant horsepower gains in the 1st power setting. Unit looks like it might have come from the Ford factory sitting on my dash. It would have been nice however, if the ads told me that an exhaust modification should be made in order to use the two top settings." —Frank D from Brookings, OR bought an Edge Evolution Programmer for a 2003 Ford F-350.
"I just recently installed the program on my wife's car.I noticed a difference right from the start. Power increased but i did notice a strange sound coming from the engine compartment during acceleration. I think it was coming from the stock breather assembly. I switched it to econo and drove it on a 2000 mile trip for a vacation. During the trip I notice an average increase of 2 to 3 miles per gallon. Not to bad for a gas hog dodge Hemi. The only dissapointment was the long download cycle. Overall I am very impressed with the product." —John L from Orange Park, FL bought a Superchips Cortex Programmer for a 2003 Ford F-350.
