Superchips Flashpaq Tuner Reviews


More power and better mpg. Stop thinking about it and get it!

Reviewed By Clint B (POCATELLO, ID) Reviewed for a 2004 GMC Yukon —9/18/2014 11:59 PM

All the tunes have a noticeable gain in power and throttle response. I use the same programmer for my 2004 Yukon and 2001 Silverado. Both are on the "mileage xs" tune. I get about 17 mpg city and 20.5 highway in both vehicles. I should mention that I also have exhaust, CAI, and shorty headers on both vehicles. All of those things helped increase mpg. The programmer was the last thing I added and it did give me an increase in mpg from what I was already getting.

Very happy with the cortex. Simple to use and nice well crafted product. It did everything advertised. When using the performance program make sure to use premium fuel, it definently made a difference

GMC Yukon Denali

Reviewed By Antonio D (Tucson, AZ) Reviewed for a 2005 GMC Yukon —4/23/2012 8:15 PM

I used the performance option and instantly felt a difference compared to stock. Also used the tow option and felt the low end torque and towed a car with no problem.
