The real problem isn't the 987 MAF or the 996, 76mm throttle body. It the stock 996 Plenum. There is a lot of engineering data some in this post.

That discuss the problem, which is the Plenum design that create a massive turbulent blockage.
Then a spin off where a members was designing a retro plenum, very similar to IPD's design. I don't know where this led after the thread died.
Intake plenum and 911 throttle body

The IPD does make this transition but the price is somewhat objectionable to some members.
