Bad mpg

[tankrc]

[h=6]I put on my 2007 gp SC a 57 Series FIPK kit. I have better off the line performance now. But my fuel mpg city and highway are getting lower numbers out of a tank of gas. The only thing i can fiqure out is that more air is going in so the car is putting more fuel in for a better air to fuel ratio. Anybody have ideas about this?[/h]

^ That is true, but not to a huge extent. More than likely you're getting a little more on the gas than you used too.

If anything you should get slightly better gas mileage because you have a new air filter on there.

The PCM/MAF adjust for how much air is coming in, adding the filter wont make a difference, car is still always calling for a 14.7:1 AFR when bumming around.

I think your foots the problem here or you need a tune up. Using 91+ octane gas too I hope.
