Thanks for the suggestion, but I did away with the fitting when I switched to blow through (a number of months ago) because of the problem you describe. Air was sneaking in at idle/part throttle which was causing turbulence.

You'd think that turbulent air would cause the MAF to see more air than there really is, but for some reason, it did the opposite. The turbulencec made me run really lean (the MAF saw less air than there was). I no idea why it works this way, does anybody else know why this would be?
