Also change the MAF sensors if they haven't been changed in the last 5 years -- you will notice a SIGNIFICANT power increase | IMO, do NOT buy new MAFs.

You might have to also relocate your IATS, but it shouldn't be expensive or hard.
Powerchip has their tune on special right now for M5board.com members: Powerchip's MAF'less tune! - The Unofficial BMW M5 Messageboard (m5board.com)
