Actually I had the cold air intake and this chip installed at the same time. According to advertising, I should be getting about 4 gallon better MPG and 35-45 hp increase with both systems installed. I have had maybe a slight increase in MPG and a noticable but undetermined increase in HP. While it is impossible to differenciate between the performance effect of the intake and the chip, I suspect the two systems compliment each other. I am satisfied with the purchases and would do it again.
