I got my 05 Mustang GT in early April 2011. After 2 months, and 7 tanks, I slapped on a CAI as I was autocrossing it and my Saturn was my Daily Driver.

Last summer I was forced to part with the Saturn, so now that the Mustang is my only car, I decided to take out the CAI and put the stock airbox back in.

Here is my data:

4/8/2011 - 6/1/2011 *stock airbox and tune*
tanks -- 7
miles -- 1769.3
gallons -- 88.281
MPG -- 20.04169
G/100M -- 4.98960

6/10/2011 - 1/11/2013 *C&L Racer CAI + various Bama tunes*
tanks -- 30
miles -- 7892.2
gallons -- 385.718
MPG -- 20.46106
G/100M -- 4.88733

2/1/2013 - present *stock airbox and tune*
tanks -- 4
miles -- 1250
gallons -- 54.447
MPG -- 22.95811
G/100M -- 4.35576

My MPGs are slowly increasing (and my G/100Ms are slowly decreasing) over those 4 tanks:
22.41 MPG, 4.46229 G/100M
22.65 MPG, 4.41501 G/100M
23.02 MPG, 4.34405 G/100M
23.88 MPG, 4.18760 G/100M

My ultimate goal is to have a 90 day average of 25 MPG, 4 G/100M. As it starts warming up, I think it will be possible this summer.



Just for comparison, all stock airbox tanks combined
tanks -- 11
miles -- 3019.3
gallons -- 142.728
MPG -- 21.15422
G/100M -- 4.72719
