1995 was the last year for the tbi and it didnt get the vortecs. 1996 was multiport with vortec heads. Just curious about the heads you are running.
I have had some experience with this and the easiest thing we found was an adjustable map sensor but if you don't add more air/fuel you really wont notice much gain.
