Oh okay gotchya. Wonder who it was then.
Im still pretty new to fixing up my mustang, so performance wise what should I do next? Also, people have been asking if I use 93 octane. I dont. Is that bad? I use injector cleaner with every other oil change.

I use premium fuel only, the price difference is not that much per tank and when you use the cheap stuff you loose a little bit of power about 20hp because the computer takes out timing to prevent detonation. Run a tank of 93 and see if you notice a difference. It shouldn't hurt anything using 87 but I don't see the point also if you get a tune you will probably need to run 91-93 octane anyway.
