"I love this unit! Drilling and tapping the hole in the manifold was a bit scary but other than that install is easy. Power is amazing this really makes the Duramax come to life!" —Chris B from Glenwood Springs, CO bought an Edge Juice with Attitude CS or CTS for a 2005 GMC Sierra.

"This is by far the best programmer for the money that I have ever seen. You can switch between vehicle model lines for basicly every GM truck 96-on. Great acceleration and a lot more throttle response and power. Overall, a great product." —Lynn G from Spanish Fort, AL bought a Hypertech Max Energy Programmer for a 2005 GMC Sierra.

"I frequently tow an 11k fifth wheel camper during the summer months. My previous tuner was the DiabloSport Predator set @ 40hp, note I have an aftermarket intake and exhaust. After towing with my new Economind/IQ setup for several thousand miles I can honestly say I've experienced noticable improvements. The best has been with observed fuel economy...when set at level 2 on the Banks system I have seen a consistent 1-2mpg increase in towing mileage (was 9-10mpg now 11-12.5mpg hand-calculated). I recently pulled in a hot, heavy crosswind and still achieved 10.5mpg! I have noticed that the DIC mileage display is quite accurate now as well, and I find that handy. Power delivery with the Banks is smoother than my old tuner and w/ much less smoke. The IQ display has really enhanced my towing experience, too. I can track digital engine temp more accurately than with the stock analog gauge. In OD going up a large hill I see about 16lbs boost, and EGT no higher than 1150deg. Downshifting produces up to 26lbs boost with similar EGT readings. Engine temp varys from 184-215deg and the engine fan cycles much less now. It's comforting to know how safe this tuner is when towing in hot & hilly conditions. Banks produced a quality product with the Economind and yes I would recommend it to others." —Aaron A from Miles City, MT bought a Banks EconoMind Tuner for a 2005 GMC Sierra, 6.6L Duramax.

Great acceleration and a lot more throttle response and power. Overall, a great product." —Lynn G from Spanish Fort, AL bought a Hypertech Max Energy Programmer for a 2005 GMC Sierra.

"I love this proggramer its works great !! Havnt had any problems with it !! I could tell it was working as soon as i installed it on my truck !!! Good gas mileage too" —Rob G from Caledonia, MI bought a Superchips Cortex Programmer for a 2005 GMC Sierra, 5.3L V8.

"I bought the Superchip to help increase the mileadge I get with my GMC 2500HD Duramax Diesel. I am getting about 2 to 3 miles more per gallon when driving 65mph." —Stewart G from King, WI bought a Superchips Flashpaq Tuner for a 2005 GMC Sierra, 6.6L Duramax.

"Just minutes to install, installed with K&N kit and really brought my truck to life, lot more towing power and a little bit of a mpg gain to boot." —Chris O from Sawyer, ND bought a Hypertech Max Energy Programmer for a 2005 GMC Sierra.

" I've used many different programmers on different vehicles and I must say this one has the most noticeable gains in torque, throttle response and gas mileage that I have seen. Highly Recommend for all Chevy applications." —Samuel F from Calabasas, CA bought a DiabloSport inTune I-1000 Tuner for a 2005 GMC Sierra, 5.3L V8.

"It seems to do what it claims, i have gained two mile per gallon and stiffened my transmision shifting. The largest gain was in acceleration which is great now. I would recomend it to anyone." —Rick D from Mattawan, MI bought a Hypertech Max Energy Programmer for a 2005 GMC Sierra, 5.3L V8.

"It is very easy to use. The directions in the box are very vague. I called superchip for clarification. I drove on a 250 mile trip on the Economy setting and saw no improvement in mileage. I have proceeded to the next setting and hopefully will see better results. It dose seem to have better throttle response. Hopefully mileage will improve." —Tom L from Logan, OH bought a Superchips Flashpaq Tuner for a 2005 GMC Sierra.

Check Engine Light On! What Do Those Codes Mean?

It was a chilly night in Montana, but crystal clear. I was standing next to my Honda, taking in the majesty of the great arc of the Milky Way. Using a cool app on my phone, I tracked the International Space Station and saw it fly above my head at 17,000 miles per hour. It’s […] The post Check Engine Light On!
