I thought the DME is looking for 2.25 or higher ohms? If I remember correctly Clark’s Garage has a write up about this. If the stock injectors are 4.5 ohms and it’s batch fire then two 4.5 ohm injectors drops to 2.25 ohms in batch fire at the DME. 2.4-2.8 ohm injectors in batch fire would be 1.2-1.4 ohms at the DME. If you add a one ohm resistor in series with the batch fire injector harness it would bring the ohms back up to 2.2-2.8 ohm range and not fry the injector drivers in the DME.

I thought the newer style , not the needle pin type were outdated compared the newer 3 or 4 hole injectors ?

Your question is kind of like asking what's the best pant size. It depends what size pants you need. 
If you put in bigger injectors without changing the tune/chips, it will just run poorly/rich. If you can adjust the tune for whatever injectors you buy, then your best injector will be one in its sweet spot for your power level. Theory aside, if you are still running the stock turbo, and don't plan to retune, then stock chips are what you want I'd say.
