I am going to be running a 95 OBD1 GSR motor.

I am dropping it in a 94 CX Hatch.

I have a gs-r fuel pump.
Skunk2 stage 2 cams, with adj. cam gears and JUN springs/retainers.

I was curious as far as the best route for fuel management would be. It was suggested to get a certain combo of these: bigger injectors, hondata, Fuel pressure regulator, V-AFC, or ECU chip.

I don't think I can afford all of these items, however, as far as I could tell the best combo would be a Hondata, and Fuel Pressure Regulator........what is the best combo for these cams and tuning????
