3000 gt turbo mass good or no good

[250lemans]

i've search for like an hour and can't come up with the answer
my mechanic told me my mass was damaged so i went ahead and bought a 3000gt tt mass but my car idles perfect but stalls when i tried to drive
do i need a 3000gt n/a mass i thought they were the same
thanks

NA one is definitely the same as ours. compare the part numbers to see if it's the same.
