"Bought this item and have used it for approximatly 3 weeks. Was very impressed with the horse power and performance as well as the increased mileage (3-4mpg. I recommend this to anyone that has an older diesel." —Dale T from Lyndon, KS bought a Superchips Flashpaq Tuner for a 2003 Ford F-250, 7.3L Power Stroke.

"The same way it increase the performance on my 7.3 diesel, it did the same to my 6.0 diesel. I was impressed how easy super chips makes it to change the performance on my vehicles. A good price to increase my fuel mileage also." —John G from La Porte, TX bought a Superchips Flashpaq Tuner for a 2003 Ford F-250, 6.0L Power Stroke.

"the max energy is easy to install and takes about 10-15 min. the programmer firmed up the shifts and has increased my full milage by about 2 mpg. no notable difference in hp. truck also has k&n system and flowmaster cat back." —Brandon P from Apopka, FL bought a Hypertech Max Energy Programmer for a 2003 Ford F-250, 5.4L V8.

"Justified the cost by a 5% assumed mileage increase (6.0 Diesel), and it's too early to say, since still "enjoying" the extra performance. Newest software has 4 modes now, adding "Economy". Gives a much improved throttle feel, less downshifting. Love all the engine stats on screen. Install instructs were terrible - doesn't tell you where to plug in EGT cable. Used you-tube videos to see others' ideas for routing it thru firewall! Just need to get a few tanks of normal driving before concluding any mileage improvement." —Matt F from Austin, TX bought an Edge Evolution Programmer for a 2003 Ford F-250, 6.0L Power Stroke.

"I was really surprised at how easy this tuner was to use and the how noticeable the results were. I paired this tuner with an MBRP exhaust system and it's like I have a brand new truck. Couldn't be happier." —Greg B from Battle Ground, WA bought a Hypertech Max Energy Programmer for a 2003 Ford F-250.

"I have an 03 6.0 Super Duty Ford I use for pulling my 31 foot Montana 5th wheel.. .The installation was simple, I set it at the lowest rating at 1 which i didnt notice any changes so I called Hypertech and at what setting could I use for pulling my trailer , they advised the third setting (3) well I did!!! Man oh man I though I was driving a Vette!!! The milage is the same and I didnt have my foot in it, Ive driven it to Morro Bay 300 miles and the milage was the same, but the power band is awesome... I run at 50 to 60 m.p.h so its not like Im horsing the rig.. Im satisfied, I just ordered a larger exhaust system should help even though my truck never showed any signs of over heating..." —Robert N from Laguna Woods , CA bought a Hypertech Max Energy Programmer for a 2003 Ford F-250, 6.0L Power Stroke.

"I have to say it definitely works. I put it in the tow mode and pulled a 16ft car hauler loaded down with junk from Little Rock Arkansas to Anchorage Alaska with my Tahoe and it pulled great and averaged about 10mpg. You can really feel the power when the modes change. Overall it is really good." —Ryan B from Chugiak , AK bought an Edge CTS Evolution Programmer for a 2003 Ford F-250, 5.3L V8.

"Have a v10 and this programmer works. Can only program only one setting though" —Jason T from Hendersonville, NC bought a Hypertech Max Energy Programmer for a 2003 Ford F-250, 6.8L V10.

"I did notice an increase in power but only about 2 mpg so far. It is easy to install but need more instructions on some of the things you can change and what effect it will have on your truck." —Eugene R from Abingdon, MD bought a Hypertech Max Energy Programmer for a 2003 Ford F-250, 5.4L V8.

"Installed and downloaded all in about 30 min. This thing gives sick horsepower in performance and extreme modes. I havent had it long enough to tell about mileage but it looks like it has come up a little. Cant wait to get a cold air on next!!" —Matthew B from Williston, ND bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2003 Ford F-250, 6.0L Power Stroke.
