What is your MPG with current mods?

 

gm stage 2, injen cai ... 21mpg

 

23 average, 30+ on long highway runs. mods see sig.

 

Stock 33-34 MPG

Stage II, GMMP Exhaust 30-31 MPG

Average speed is 55 MPH.

Remember the more boost you run the more fuel you'll need. Also, with cooler air your engine is getting more air so it will need more fuel, so expect your MPG to drop 1 or .5 MPGs as it gets cold.

 

Stock: City ~ 23

 

21 around town and 30+ on the highway depending on if I am going the speed limit or not. I have seen it hover around 40 MPG at 55mph since the Injen CAI.

 

right around 25. K&N Typhone intske

 

My gauge says I am averaging 23.8mpg

I do a lot of city driving. Mods are in my sig.

 

True, but the converse is that the engine doesn't need to work as hard when it has extra oxygen (ie you don't have to step on the gas as hard) so it doesn't make much difference. In fact, this time of the year when its nice and cool before winter and oxygenated fuel I usually get the best gas mileage.
