Yeah I have a 2012 Eco with the 6M and the tune surely wakes the car up. First things first: Check the spark plug gaps to make sure they are all @.030 There were some cars found the gaps were all over the place . Running premium 91/93/94 what ever is avail in your area is recommended. It wakes the 1.4 Turbo up once it gets used to it. Tuning also from BNR is another thing you can do to wake the car up and give it more power. The tune you get from BNR is allows you to turn it on or off depending on whether you Cruise Control is on. As far as the MPG, that will depend on how well you can stay out of the accelerator with the added power. At times I have trouble with that living in a very hilly area.
