ONLY if your engine is radically ported with either a HUGE street port or a bridgeport will swapping to TII manifolds of be any benefit. And you will need a standalone to tune it.

why would you need a tune if your still using a n/a maf?

At that point, you probably won't be running the stock AFM, even yet, stock ports. Really no point unless you read what Aaron said... If you do put them on the stock N/A engine, it will most likely make you lose some power. No auxiliary ports, shorter intake so power suffers at higher RPM, ect....

Sigh.
THE ONLY REASON TO PUT TII INTAKE MANIFOLDS ON AN NA IS TO EITHER TURBOCHARGE THE ENGINE, OR BECAUSE YOUR PORTS ARE SO AGGRESSIVE THAT THEY OVERWHELM THE NA INTAKE MANIFOLDS.
So unless you have a monstrous street port (and I mean the kind that makes peak power at 10,000 RPM) or a bridge port, you will gain a big fat NOTHING from putting the TII intake manifold on the NA engine. In fact, you will probably lose top end due to the shorter runners and crappier transition to the port runners, and you will lose a bunch of low end due to having the aux ports open all the time.

I have the turbo II intake on my s4 N/A block which is turbocharged. I did not port match the intake and it feels great, no problems that I notice. Do you think there would be a gain by porting it, or rather a loss in low end and gain at the high end? The drive-ability under 3k is the same just as it was when N/A. Hope im not thread jacking
