CMC - Clutch Master Cylinder
CSC - Centrifugal SuperCharger or "Clutch Slave Cylinder"
DD - Daily Driver (versus perhaps 'Track' or 'Drag Race' purposes)
EH - Exhaust Headers
FI - Forced Induction (either Turbo or Supercharger) OR "Fast Intentions" (aftermarket exhaust and other products)
HFC - High Flow Catalytic Converter (Cats)
LSD - Limited Slip Differential (? - uncertain)
LTH - Long Tube Headers
NA - Naturally Aspirated (non-turbo or non-supercharger)
OEM - Original Equipment Manufacture
PSI - Pounds Square Inch (referring to "boost" pressure)
