Need help on tuning ???

I have to disagree. DSMLink is far more superior than an AFC setup no matter what modifications you have on your car. Then once you have it you dont have to upgrade again just to run a bigger turbo/injector setup.

I was just talking about this with another guy. He wanted to do the same thing. Running 660s and the AFC your timing is going to be quite high and your air flow is going to be a lot lower considering the AFC just lies to the computer.

I'd suggest save for DSMLink and for a wideband O2 or dyno time. Get the big stuff now, like if you get DSMLink you can choose any injector you want from 450s to 1600s and run them with whatever setup you have then never have to upgrade again. For example: You could have a completely stock engine bay, turbo and all, and with DSMLink you could run 1600cc injectors and have it run/idle like it has stock injectors in it and still maintain stock fuel mileage. Kinda overboard but you get the idea.

DSMLink would be the better choice in my opinion.
