"works great just like they said it would,will recommend to my friends."

"I Have a 02 Dodge 3/4 ton, the power curve is much higher, no dead spots, empty I now get 19.6mpg , loaded 15.8--at the pice of fuel this will pay for it's seft in less then two years. Thanks Hyperteck"

"program for 87 octane. Noticed sharper responce, about 1 mpg better on gas, firmer shifts. Not bad. Worth it in the long run. Stock suv with only K&N replacement air filter."

"This was a birthday present for my husband. He plugged it into his 98 Ram Air as soon as he had the wrapping paper off! We noticed a difference in the sound and performance of the car immediately!"

"I installed this on my 2004 Dodge Ram with the Cummins diesel. I'm using stage 3 and my truck pulls my 9500 pound trailer without breaking a sweat! Much quicker throttle response and has added about 1.5 mpg when not towing. My towing mpg has stayed about the same or maybe a little lower, but the power increase makes it worth it. Paid $249 for the Hypertech Programmer which is about 1/2 the price of other diesel programmers and chips, so I'm very happy with my new Hypertech Programmer III purchase. Not only do I get better performance, but I can clear check engine codes and I can change from stock to level 1, 2 or 3 in a matter of minutes, and when I take it into the dealer, I can reprogram stock settings in less than 5 minutes. I can't comment on gas engines, but if you have a diesel, I'd say BUY ONE!!!"

"i used it and noticed a big differance in shift firmness and difinatly like the improved shift points. i noticed a improvement in in mid and high range power. i cant tell about gas milage i have a heavy foot. i recomend it for anyone who wants better shifting"
