i had installed it on my car and had it on for like three weeks and found out that it doesnt help at all about gass milelage. made the car more responsive on the gas and had a better idle. but from 32mpg went to 26mpg O_o... no deals on this product. i guess it works better on other cars but not so much our car from lack of power.. what u guys think. i uninstalled it today going to see if it was really that much of a problem..
during driving i was never on full on the gas.

 

those things dont work. If they did all cars would come with them from the factory.

 

but how can u explain the mpg loss?
