Those that have done the 987 airbox, with 74mm TB and either IPD or 997 plenum, what were the measured gains from the airbox on it's own? I have the TB and plenum that I will be installing, and trying to decide if the airbox is worth it. Seems a LOT of work to manage the MAF issues as well as tuning (I don't have PIWIS to download a tune on my own) especially if the gains are nominal. Would love to hear some feedback either way.
