987 v 986 Air box

[Pololo_Boxster]

Reviving this thread, if it's OK with members..

I am going to start doing this upgrade with my 2000 Boxster 986S..

So far I have the following:
1) 987.1 Airbox with the MAF section
2) 74mm TB from the 997
3) Plenum from the same 997

Still a bit confused if I either need to use the 987 MAF or the 986 MAF along with these upgrades?

If I go with the current 986MAF, do I need to have it tuned?

When do I need to have it tuned? if so, what's the best way to do this?

My apologies if this has been covered already... I read through all 16 pages, but still a few questions left..

TIA,
Regards
