New to the scene ,1991 Mustang

This past weekend I bought my first mustang. Its a 1991 red lx hatch 5.0l 5 speed. A few mods that I know of on it are bbk cai, bbk 75mm maf, trick flow upper and lower, 24lbs injectors, bbk shorty headers with full exhaust and ford motor sport mufflers, and I believe the clutch was a king cobra (I think). I have been around mustangs with my friends but never really worked on them other than general maintenance.
