987 Airbox and 74mm TB: MAF and tune issue

[dlud]

I have a 2000 S (3.2) and am in the process of putting in a 987 airbox and a 74mm throttle body. I've read much here and at other sites about this process and remain bewildered as to the best solution for the MAF and whether a tune or new ECU map will be required. So....

1. Is the best solution to use the 987 MAF tube/holder? (or alternatively hack the old 986 MAF tube onto the 987 airbox?).

2. Use the 986S MAF or the 987?

3. Use the stock 986S tune, another Porsche tune or custom?

I see a lot of back and forth in the forums on these issues but don't see that there was a final "best practice."

What combination has worked for a 3.2?
