Well it sounds like my car is running like it should then. It's the design of the car to idle at 1500 until you come to a complete stop, then it goes down to 900rpm or so, like it should. So I don't think there's a problem. Why are you saying to put the stock intake back on then?
I filled up last night and got 33mpg this time! That's a huge gain...I'm thinking it's because the ecu finally reset itself. No way am I going back to stock if I'm getting way better mileage! I don't care if there was a power gain or not.
