No, you don't HAVE to have a chip, but if you want it to work right, then the chip is a must. The '02 gt maf is superior to the lmaf for n/a cars, might be a different story with forced induction.
You will need a newer maf wiring harness, i think '96-'97 mn12s or '96 up gt stangs will have the right one, but not sure. Also, need an adapter to mount the maf
