It wasn't explicitly clear.....Is your buddy running a 987 MAF housing with the standard diameter? 80mm diameter was mentioned. How are you deeming the engine to be running rich?
Thanks Jay! Richard is running the 987 airbox but has kept the MAF and housing from the original airbox to try to avoid any ECU problems.

Neil,

Retaining the 987 MAF housing could itself can cause ECU issues as the diameter is larger than the 986 housing iirc. I have heard, stories where the ECU may adapt but I tend to take these with a grain. Unless your friends custom tune is geared for a larger diameter, he will likely get mixture issues.

987 Airbox +986 MAF tube+986 MAF sensor is no problem on my 986 S . The airbox is not critical within reason. Boxster CAI systems have no real airbox at all.
987 v 986 Air box
