"Had a minor increase in off the line power. Not as much as what i would have liked but it does the job. It really hasn't helped in my gas mileage like it is advertised to do. All and all it was a good investment." —John M from Sparks, NV bought a Jet Performance Module for a 2003 Dodge Ram.
"I like all the features of the Hypertech Programmer with the exception of the wheel size correction not being available for my vehicle. I also have the Superchips programmer and have to use the wheel size adjustment from their programmer. The Hypertech still has more features and adjustments than the Superchips model." —Albert R F from San Antonio, TX bought a Hypertech Max Energy Programmer for a 2003 Dodge Ram.
"I installed on my 03 dodge ram 4.7 4x4 and this thing has done wonders, i have installed a cherry bomb extreme dumped before the rear axle, an afe CAI(stage 2), airraid poweraid TBS, and now the flashpaq, the 4.7 weighs a ton even being a single cab and now my baby girl really giets ups and moves, i love all the features(0-60 in 8.91 sec, got to be a record for the 4.7 lol)and has really helped the overall preformance of the truck. i am getting about 14mpgs with mostly city(country back roads) and some highway(hard to stay off the pedal with the Cherry Bomb lol, i get about 19-21on the highway depending on highways and speeds between 65-75. overall an amazing product, would deff recomend and buy again, just a little pricey" —Jeremy D from Willis, TX bought a Superchips Flashpaq Tuner for a 2003 Dodge Ram.
"I could feel the difference as soon as I started to roll down the street. Once on the highway it was very clear there was a big increase in horse power. Quite satisfied." —Richard C from Walden, NY bought a Hypertech Max Energy Programmer for a 2003 Dodge Ram.
"I ordered that flashpaq as a christmas gift to myself and after getting it, I read all the directions before the install. Now after using it for about 4 weeks I love the performance tune. My shifts are better and you can honestly feel the power difference." —Michael W from Chico, CA bought a Superchips Flashpaq Tuner for a 2003 Dodge Ram.
"Well worth the money. Makes a big difference and very easy to install." —Eric L from Mcminnville, OR bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2003 Dodge Ram.
"I am not sure if it is worth the price yet or not, the truck always had enough power pulling with the HO diesel. Was looking for better fuel mileage pulling. Seems to get about two miles to the gallon better without pulling, according to the computer, but haven't actually figured it up yet, and I don't usually drive it without the trailer. Going to try different modes and see what happens. I can't really say I am disappointed, but maybe I expected too much. Was really interested in fuel mileage increase rather than more power." —Craig D from Sabetha, KS bought a Hypertech Max Energy Programmer for a 2003 Dodge Ram.
"i am impressed with the gains ive made with my tuner. definite power gains on performance. i have a 2003 dodge ram 1500 5.7 with k and n intake system and a poweraid throttle body spacer and after installing the bullydog it improved drastically on torque. definitely worth its price." —Jamie K from Stuart, FL bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2003 Dodge Ram.
"I bought this super chip for one reason to save gas. I own a Dodge hemi and it eats gas. The website was very confusing no answers no help, the updates the login the help was just not there. Of course it was the weekend and super chip has banker hours. On Monday I got a hold of them. They answered my questions fully. Now everything is well. Downloads to the truck, are unknown. Lots of times I have to download it twice, but when the right download is in the truck. I do notice a difference in how the truck feels and reacts especially in the performance mode and especially in the towing mode. The economy mode gas saver does the trick to, actually got 3 miles per gallon more, that's big for a hemi." —Steven B from Glendale, AZ bought a Superchips Flashpaq Tuner for a 2003 Dodge Ram.
"Very easy to install, seem to notice slight power increase along with small fuel use improvment. 5.2 dodge" —David D from Wichita Falls, TX bought a Superchips Flashpaq Tuner for a 2003 Dodge Ram.
