I left it out for 2 days to see if the computer would start to accpet it but it didn't. I even disconnected the battery try to have the computer relearn everything but its a 1990 I don't even think it does that. :?

A gutted airbox won't work out too well if you try to remove the screen. You need smooth, laminar flow, and a GOOD cone filter to make it work.

Mine idled rough for about 3 minutes, then settled right down (this was after the intake install). With the modified stock airbox, my idle never settled down.

This is a 'feelable' mod, will not hurt efficiency, and does seem to add performance.

3 (at least) of the 5 fastest Bonnevilles all have their MAF screens in. Your mileage may vary.

Cheers,

Maybe I'm just lucky, or may NA vs SC makes a difference, but all I have is a gutted and opened airbox, stock "crinkle tube", Fram AirHog filter, and my screen is on a shelf above my computer. I have no idle problems, and can't remember ever having any.

maybe the happy medium is to cut the maf screen apart so that the only part that still has a honeycomb around it is the area up by the maf sensor itself.

anyone here done this before?

The mesh is very flimsy. Last thing you want is weaking the screen to the point that massive air flow at wot crumbles it into the intake.
