97modifiedmustangGT

i have a 97 GT and i want to know how to ajust my timing since i have the piggyback syle UDP's and i heard the steeda timing ajuster doesn't work with that syle pulleys. and my tuner doesn't ajust timing. is there anything else i can do?

You will need a different tuner or replace the pulleys and add the timing adjuster. No other way I know of.
