"sweet upgrade and simple to use... adds so much to my truck its like having a new toy. softwares pretty easy and straight forward but i did have a problem updating it. it didn't finish updating and errored out but i just continued the download & after numerous attempts, it worked. i'd give it a 5 out of 5..." —Rod Q from San Jose, CA bought a Superchips Flashpaq Tuner for a 2005 Chevy Silverado.
"I have been a Fleet Manager for over 33 years and was always sceptical about fuel mileage improvers. If I hadn't seen it for myself I would have said that the 4 to 5 mpg improvement was unlikely. That and the great improvement in power makes this a great investment. One hour to install. Had a question for Bully Dog tech support and got to talk to a human with the answers. The Bully Dog, Duramax, Allison make the greatest combination." —Mike C from Zapata, TX bought a Bully Dog Triple Dog GT Tuner (49-State Legal) for a 2005 Chevy Silverado, 6.6L Duramax.
"For the money it is a good product. The features r great. Would recommend this product to friends and family." —Justin M from Vina, AL bought an Edge CTS Evolution Programmer for a 2005 Chevy Silverado.
"When my truck was stock I was getting 18 to 20 MPG with just a K&N Filter kit. Then I put a 3in lift on it with bigger tires and lost 4 MPG. Now after I program it I'm back to 18 to 20 MPG and more snap when I need it. It was well worth it. Thanks" —Ty R from Arena, WI bought a Superchips Cortex Programmer for a 2005 Chevy Silverado, 5.3L V8.
"The E-Con is very easy to install. It saves around 2-3 mph. However, I would like to see a better description of the difference between the settings, A and B. But overall, this is a good product." —James M from Williamsburg, KY bought a Hypertech Max Energy E-CON for a 2005 Chevy Silverado, 6.6L Duramax.

"What a great product, I had so many excuses from GM and the dealer. It was easy to follow the instructions and what a change in my truck's performance. I had the gears changed and bigger tires,all the dealer wanted to do was sell me a newer truck." —Jerry W from Shelton, WA bought a Jet Performance Programmer for a 2005 Chevy Silverado.
"I havn't had this programer long enough to really know how much it has improved gas milage but so for I have at least seen a mile plus per gallon improvment. I like the adjustments that can be made like the shift points, shift firmness, tire size etc. I would say over all this programer is worth buying." —Ken T from Pleasant Grove, UT bought a Hypertech Max Energy Programmer for a 2005 Chevy Silverado, 6.0L V8.

M from Nogales, AZ bought a Superchips Flashpaq Tuner for a 2005 Chevy Silverado, 5.3L V8.
