Bonee Stockk

So basically i just want to see other peoples opinions on what i should do to my stock mustang gt. I have around 12k to spend on it and its got 180k miles not sure if engine or tranny has been replaced. I have done the basic spark plug swaps and cold air intake install. I looking for much more power under the hood, any suggestions?
By the way its a auto tranmission.

why? why would not knowing a power goal, money limit, et goal, n/a or power adder suggestion, any experiences in building modular motors ever blow your mind?
