Even me being perfectly happy with the performance under the hood of my baby, I still went the Tune route right away hah. The tune will just feel so much better I promise you that. Then after that get onto the appearance stuff. I love doing things for looks because for me it just makes the car mine more obviously, it's not just another mustang, it has my mods that anybody can see. But be patient though! lol the faster you run out of mods the faster you'll want to jump into another car
