"I had just lifted my Z71 and put 35" tires on it so I needed something to get the power back I had lost. I used the performance tune and re-programmed the ECM for the larger tires and firmer transmission shifts. Using 93 octane fuel, the programmer woke up my truck! It brought my truck back up to stock power levels and then some! I love this programmer." —Adam S from Senoia, GA bought a Superchips Flashpaq Tuner for a 2007 GMC Sierra, New body style, 5.3L V8.
"Happy with the overall install of this item. Currently have it set on performance and the upgrade is well worth the money. I will be purchasing edge products in the future." —Aaron O from Victoria, TX bought an Edge Evolution Programmer for a 2007 GMC Sierra.
"Very noticable increase in H.P. plus a little in gas mileage but is way to much fun in power setting. Also matches interior and lighting great!" —Brandon J from West Fargo, ND bought an Edge Evolution Programmer for a 2007 GMC Sierra, New body style, 5.3L V8.
"Excent product worth the money. Gave me 2mpg in the city and 4 on the highway. Can definatly tell the power increase. Easy intilation and all you had to do was answer yes or no." —Cody V from Cullman, AL bought a Hypertech Max Energy Programmer for a 2007 GMC Sierra, New body style, 1500, 5.3L V8.
"I was impressed with the performance gains. I'm running it on level 2, level 3 and my MBRP cat back free flowing exhaust causes an EGR DTC to be thrown. Not surprising. Known issue, and fix is not worth the effort and dealing with the dealer for warranty service. Fuel economy didn't get any better, but temperatures have gone down and my fuel goes south anyway with cooler temperatures." —Robert S from Cordova, TN bought a Hypertech Max Energy Programmer for a 2007 GMC Sierra, Classic, 6.6L Duramax.
"I have a short drive to work and used to average about 10mpg on that drive, and after install I am averaging 11mpg. While going 62 on the highway I got 25mpg. Normally I get 19-20 on that drive. There was a slight tailwind, but not enough to add 5 MPG. This was definitely worth the investment!" —Scott V from Columbus, NE bought a Hypertech Max Energy Programmer for a 2007 GMC Sierra, New body style, 1500, 5.3L V8.
"First off, I have a 2007 new body style 5.3L V8 GMC Seirra.
I have flowmaster exhaust and a cold air intake. I also have a 7 1/2 inch suspension lift with 35's. When I first got the lift installed I noticed a huge decrease in power. I drove about a week without a chip then I got the hypertech max energy and wow, it returned that back to stock power and more! It also helped on gas mileage 2 mpg difference! This Product is great. I highly recommend it!" —Patrick F from San Antonio, TX bought a Hypertech Max Energy Programmer for a 2007 GMC Sierra, New body style, 4 speed transmission, 5.3L V8.
"Have a NBS 07 GMC and this is an excellent product.. Has tons of features and is easy to use.. on dash monitering is great as I am an engine buff.. with edge, flowmaster, and K&N filter. managed a firstname.lastname@example.org in the quarter.. not bad for a otherwise stock truck.. Also getting a little better gas mileage on the highway.. Seems to stay in V4 mode a bit longer... All in all I like it." —Carl B from Duson, LA bought an Edge Evolution Programmer for a 2007 GMC Sierra, New body style, 5.3L V8.
"I have had my bully dog gt tuner for about two weeks and my reason for buying it was gas milage . I own a 2007 GMC crew cab with the 4.8 V-8 in it,my truck has 22s on it so the truck only gets 13 miles to the gallon . After i installed the tuner it gets 16 miles on regular gas and 17 miles on prem. I still can`t believe that it made that much difference, you will need to keep your foot out it ! Overall i am very pleased and i highly recommend bully dog. Thanks Bully Dog, worth every penny !" —Steve O from Porter, TX bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2007 GMC Sierra.
