Which injectors

[toad]

I have a 1996 f-250 crew cab 7.3. Current performance mods include, php 6 postion chip 80 daily, 40 tow, and 60 tow, hypermax intercooler, intake and exhaust. The tranny was rebuild last fall with all heavy duty cluches and torque convertor. Gauges are sitting on the shelf still I guess they dont do any good there. I have this nagging need to modify and change things. I am wanting to get more power. I have looked at Full Force Diesel injectors a little. My question is would I be better of just going with the stage one injectors? or going to the bigger stage 3 205 cc hybrids? I dont want to sacrifice fuel mileage, driveablity, and reliablity.
