Default What are symptoms of a damaged MAF? more inside....

we VAGd my friends car last night and his MAF was flowing ~250G/S, and we logged it today after we removed his intake and reinstalled it, and his peak MAF is 234 G/S, and his FATs time is .5s slower... no codes and no CEL...

MAF hits 231 at ~5600 rpms, and it seems to level off there for the rest of the RPM range all the way to 7k...
the intake is an S-flo with darintake hole... maybe the MAF isnt seated properly on the airbox?

Thanks for any help

Stock? Chipped? Model year?

Default Sounds like a bad MAF. A chipped S4 should read 250-280 g/sec.

I would put the stock airbox back in to rule out the intake as the culprit first, though.
