"This Superchips programmer is a must have. It gave my car nearly 30 more HP and torque. I did also add a K&N cold air intake to go along with the programmer. I can tell the difference in speed, and my MPG is at about 20 mpg, which is a 4-5 mpg gain from what I initially had. Just a final note, don't fall for those scams that say you can increase horsepower up to 50+ for a low cheap price, they don't work. If you want true gains, it will cost more than 100 bucks. But overall, this is my second CAI and Superchips combo, and I am completely satisfied."

"The ease of installation was better than what I had anticipated. The programmer housing was an exact match to my dashboard, and the appearance of the unit looked factory installed. I have only had the programmer for a short while, but enjoy the fuel savings already."

"I have a Pathfinder V6-4.0L. The gas mileage was at 8 miles per gal. It was blowing more gas out the tail pipe than it was burning. Somehow my computer had got out of calibration. So, I bought the Hypertech to reset the computer. The product was very easy to use. It's very simple, just plug in and follow instructions. I completed my computer reset in 10 min. I took my Pathfinder out for a test run. To my surprise, it ran great and shifted out at 6,000 rpms in every gear. It was very fast and smooth. I get 19 miles per gal now under normal driving conditions. Between 55 and 60 miles per hour. This is an excellent product and worth every penny I paid for it. There is a 5-star rating, but I give it a 10. If you have a truck or car and want better gas mileage and passing power, buy it. Find the right Hypertech programmer for your vehicle. Billy M. England"

"Installation is easy on the new 2012 Dodge Durango. MPG average went from 14.8 MPG on the HEMI to 15.8 MPG on the next tank of gas, driving the same route. Well worth it. Already I can feel the added horsepower as well."
