"I installed this product on a 2004 gmc seirra w/ 5.3 litter. The power was noticed right away.I also installed the k&n air intake and only noticed about 1mpg better" —Andrew M from Copan, OK bought a Jet Performance Module for a 2004 GMC Sierra.

"I have a 2004 gmc Sierra 2500 and the edge programmer is good for it. I bought it mostly for its economy mode, which has turned out good. I would say that it improves the fuel economy on the gravel by about 1 mpg, 3-4 mpg on highway, and 2-3 mpg in the city." —Josh W from Onida, SD bought an Edge CTS Evolution Programmer for a 2004 GMC Sierra, 6.0L V8.

"It is hard to find anything to help out a 2.2 S10 and this is one of the few items out there. Once it was put on I could tell a huge difference in just the way the motor ran. Acceleration was quicker and smother, and I found I need to set the cruse just to go around town. I have done some mods to my truck and this just puts the icing on the cake!! This is a must- have for anyone with a 2.2, it's also the only module out there!" —Jonathan R from Indianapolis, IN bought a Jet Performance Module for a 2004 GMC Sierra, 2.2L CPI 4-cyl..

"I purchased the Edge Insight CTS because it is capable of supporting selectable both add-on performance programs and accessories. Installed the system on GMC 3500 with Duramax diesel. Also installed an Edge EGT accessory. Installation of CTS unit was very easy; EGT accessory took some time to install (as expected). I am very pleased with system appearance and performance. Lots of user selectable displays and options." —Gregory B from North East, MD bought an Edge Insight CS/CTS Monitors for a 2004 GMC Sierra.

"I have tried all modes except tow mode. I was unimpressed with both 87 octane and mileage saver. I however am very impressed with 91 performance. It gives you the most power while giving you the best MPG increase! Will recommended to everyone i know!" —Thomas B from Lake Villa, IL bought a Superchips Flashpaq Tuner for a 2004 GMC Sierra, 5.3L V8.

"so far this tuner is pretty cool. has a lot of adjustments that the user can make on their own or do the datalogging and get help from tech support." —Joseph L from Marksville, LA bought a DiabloSport inTune I-1000 Tuner for a 2004 GMC Sierra, 5.3L V8.

"Awesome! State police said "I wish my police car could accelerate like this." Haven't used the tow setting yet, but with the performance results I got, I have no doubts it will be awesome too." —John Jeremy B from Las Cruces, NM bought a Superchips Flashpaq Tuner for a 2004 GMC Sierra.

"Easy to install. I'm a watch the video type guy...(i hate to read..especially small print) I wish the had a library on YouTube of how and what the fine tune adjustments will and will not do to performance or gas milage. I do like the the performance on 92 octane.. Wow!" —Joe L from Lakeside, CA bought a DiabloSport Trinity T-1000 Programmer for a 2004 GMC Sierra, 5.3L V8.

"Setup is easy and quick, cool and fast way to improve performance to my 5.3 sierra. I like that it has the engine load and throttle position on display if you want to have it on while you drive. I would recomend for it for someone who wants to do a quick tune to their truck" —Victor C from Pasadena, TX bought a Superchips Cortex Programmer for a 2004 GMC Sierra.
