Dumping the PCV valve makes it easier on me. I'm dumping the EGR for flow reasons.
No reason to use stock early EFI injectors if you are running a Megasquirt. Those injectors command collector prices. They are also low impedance and place different demands on the switching semiconductors. Better off with a common newer type. I'd ask around on the Megasquirt message board to see if anyone knows what else fits in there. Keep the PCV. Keep the EGR unless you are trying to make every last drop of power and completely ignoring economy. It should not make any difference at wide open throttle but can allow you to use more timing at cruise.
PCV is Positive Crankcase Ventalation... which is just that... it allows the blowby gasses to be recycled.... without it, or with a bad PCV valve, the engine can sluge up rather easy...
the blow by gasses are whats left of the fuel/air mixture, that managed to slep between the cylinder walls and the rings... blow by..... now all that stuff is stuck in the crank case with no where to go... but the PCV valve simple takes that gas and usually dumps it in the valve cover or intake manifold... I vote to keep it, it does no harm and a new PCV valve is $3.
