If you're going to get a reprogrammed chip, Darth would be the one, but you don't necessarily need it. Why do you feel you do? I'm running a 3.4 in mine on a stock ECM, and I personally know of 3 others doing the same. The only thing you would need do is replace the Fiero injectors or the original 3.4 injectors with a pintle or modified pintle style injector rated at 17#.
The stock fiero ECM will run a 3.4L . For optimum results though, I recommend that the base Pulsewidth Constant be adjusted in the program as well as the fueling above 3000 rpm. Depending on the plenum you use the fueling needs will change. The Fiero plenum really chokes this engine of air at the top end. You can adjust for it but porting the plenum and adjusting the program yields better results.
