Which way would you go on a DD automatic car ?
It sounds like you're on the right track! Bama tune, Airaid intake and Gears are the three most beneficial mods you can do for any Mustang, especially the 2011+ GT's. You'll notice huge gains in power, torque, acceleration, drive ability, gas mileage, throttle response, shift points and much more from the tune! The intake will definitely add some power and a ton of engine noise.
Last but not least, the Gears! This is my personal favorite mod for sure. This will help you get off the line a lot harder and the car will be much more fun to drive. If I were you, since it's an AUTO I would probably go with a set of 4.10 Gears. 4.10's are a little much when you have a manual because the transmission ratios are different and you actually have to do the shifting yourself! But the AUTO's love that gearing.
This is just my recommendation. I hope this helps! Definitely let me know if you have any questions or need some assistance in the near future.
