"This thing preforms as advertised, adds some power for sure. This is mainly done through shift points etc, but is fun none the less. I did not purchse this for fuel economy, so I have not tested that program. Service from superchips is lacking to say the least, I have emailed them a couple times and have yet to recieve a reply. If you have replaced your stock radio beware, as you will have to play with the wireing a little before programing your vehicle. This is something superchips has not mentioned and not replied to. Other than that a fun product that does indeed change the way you rig will run, and it is easily noticable."

"I have a 1500 4.8L and would max out at about 55 pulling an 18ft toy hauler. I can now go 65 to 70 but went down from 14mpg to 8mpg in tow mode. Needless to say I will be looking for a larger truck before next season but in the mean time the Super chip has helped some."

"This is a great value. The cortex is an amazing programmer that does just about everything. There isn't a better option out there and autoanything has the best prices. I have a lot more power, torque, More responsive and agressive. I'm running it In performance on my 2005 5.3 silverado and I've seen 2-3 mpg gain city and a 4-5 mpg gain highway. Amazing product....worth the money"

"Couldn't be more happy with my Superchips programmer. I bought it for my 2007 Chevrolet Silverado LTZ. I had the truck lifted six inches and installed some 20 inch rims with some beefy BFG's. Looked great but lost a lot of horsepower with the big rims and tires. This programmer really kicked it back up plus added more than what it had. I also switch it to tow for when we pull our trailer and up the mountain we go no problem. Great addition. Would recomend to anyone."

"Extremely easy to use & noticable increase in throttle response/HP. I have a smaller V-8 so I'm always looking for ways to squeeze out every last drop of HP possible w/o breaking the bank, & while it's a great mod to add to your truck it's not the final solution...there's always something else you can tweak or add for a bit more power & speed. I will say that it's like driving a totally different truck. Stop comparing websites, prices, brands, etc & just get it...you know you want it or you wouldn't be reading this! It'll be there in a few days, you'll be like a little kid on Christmas day, & best of all you can start looking for other ways to beef up your ride. Later"

"This is a great product, I have added JBA headers, K&N cold air intake, duel exhaust, better plugs and wires, and now the superchip. My 2003 Chevy Silverado Z71 is alive, just wish that to adjust the trans shifting had more literature on better adjustments. Anyway all and all AWESOME!! Thanks"
