Does anyone have the MAF spec at idle? (g/s)

Alldata doesn't show a spec for the supercharged engine.

Thanks

Thanks so much Matts Auto,

I'll get my scope on it shortly and a sensor sim to compare what the ecm is seeing for g/s!

Actually you might better use the scanner to view the maf-frequency , best as graph. The scope is not of much help on these kind of sgnals unless you used it as a graphing multimeter as the snap on scopes are capable of.....

Thanks, but I can get Frequency on my scope. My concern was originaally on a non supercharged 6.2l id expect to see 6.0 g/s or better at idle., this being supercharged is 3.2g/s at idle, just need a something to compare against is all!
