a ported tb isnt gonna change fueling much. even going from a 99+ tb and maf sensor to a ported 97 tb with the 99 sensor didnt put trims too far off.
the dia of the maf sample area isnt any larger so the maf will be pretty close....
now if its a ported tb with an external lq4 (or any not stock junk, like a 99maf in a 4" tube, etc) then youll need to change tables.
important thing is to never beat on your car after a batt disconnect/hard reset. the farther off your tune is the pcm will adjust for it, but it needs time to figure out how far off it is and bring trims into line...but the ported tb with the oem type maf sensor in the oem location should be fine.
