Just to clarify what "the Formula option" is:
WS9 = MODEL CONVERSION FORMULA(MERCHANDISING OPTION) FORMULA(WS9)
ALL V8 Firebirds have RPO WS9, which is why some T/As have "Formula" on their registration info or insurance info. The state and insurance companies only care that the car has a V6 or V8.
W66 = FORMULA OPTION(MERCHANDISING OPTION) FORMULA(W66)
ONLY Formulas have RPO W66 (but they ALSO have WS9).
Y82 = TRANS AM PKG BASE(MERCHANDISING OPTION) PKG,TRANS AM BASE(Y82)
ONLY Trans-Am Coupes ('94+) have RPO Y82 (but they ALSO have WS9).
Y83 = TRANS AM PACKAGE(MERCHANDISING OPTION) TRANS AM(Y83)
Only Trans Am Coupes ('93-'95) have RPO Y83 (but they ALSO have WS9). It appears that only 5 '95 T/A coupes got Y83, the rest got Y82. These were very likely mules or pilot cars before GM settled on Y82 for coupes exclusively from that point on.
Y84 = TRANS AM GTA OPTION(MERCHANDISING OPTION) TRANS AM GTA(Y84)
ONLY Trans-Am Verts have RPO Y84 (but they ALSO have WS9). Interestingly, 3 T/A 'verts in '94 appear to have received Y83 instead of Y84 according to CompNine's database. These were very likely mules or pilot cars before GM settled on Y84 for 'verts exclusively.

The reason behind this is that the VIN isn't trim specific, just motor specific (ie, it just indicates it's a V8 car), so all V8 cars will have something like "Firebird Formula Trans Am GT" or something to that effect on the title or when you run the VIN. It doesn't mean your Trans am is a Formula, or your Formula is a Trans am ect...
