I have to say I believe it is the amount of air going past that causes the lean condition. Makes sense because a lean condition is caused by too much air to fuel ratio. Just like exhausts being opened up and less restrictive causes lean conditions. I can't seem to agree anything other than the more air means leaner conditions regardless of MAF location. Simply put, more in & more out means the computer has to account for than it is initially set up for. Fuel seems to be the missing ingredient. Or Bill for that matter. LOL I seriously can't wait to install my gryphon and see the difference. Hope my thoughts help.
