Bingo.

There are 2 things that essentially "decreased my mpg". The tune, and my catback. Why? Because both things exponentially increased the reward on my senses when pressing down on the accelerator pedal as hard as I can!

Oh, but the sound is so rewarding to the senses indeed.

Guys guys, I don’t think type of fuel is the issue here, last week i filled up my tank and it showed a range of 310 kms but only run for 288 kms.. an avg of 14.5L per 100kms.

Do you think, does retuning the car makes a difference?

2015 ECOBOOST I WENT WITH THE COBB STAGE 1 93 OCTANE TUNE AND ACTUALLY GOT 2 MORE MPG DIDNT HAVE TO PUSH THE GAS PEDAL AS HARD TO MOVE THE CAR ... VP

The GT models have a gas tank with .5 more gallons then the Ecoboost models. I Daily a Hybrid that is supposed to get 39 MPG but have been getting closer to 33 MPG because its boosted and I sometimes have a lead foot. When I tuned my Mustang I started getting closer to 28 MPG if I drive it very conservatively.

I usually get 26 to 27 with mods in orlando
