Im not sure if the injectors are any different, but I run my 3.1 with the injectors from the old 2.8 engine. Seems to me Ive read that the injectors from a Fiero are the same as a typical 2.8 but a little more flow.

Id look on ebay if you havent already. Sometimes they list injector flow rates on there. Other than that, maybe try looking up your injectors on Advance Auto Parts and see what all fits yours, then check out a smaller or lower performance vehicle that you know has the same engine.

Another possibility is to install an adjustable fuel pressure regulator, then run it a little on the low side. Youre bound to get less fuel through that way.
