MAF Sensor on crack???

[Kappa9012]

yep another lmm Maf issue.

So i data logged my MAF sensor since I was getting a p0108 MAP voltage signal high. When I logged it I see the frequency is going above 10,000hz. I noticed in EFI live, the map only goes to roughly 8600hz.

Is my MAF sensor bad? or is it normal to for the sensor to read above the map range?

i see a lot of posts about lmm's having maf issues. And it's a new twin kit. s480 over stock.

Is it a 4" intake. If so that was my issue. Went to a 5" and it quit

Who is tuning it? May be a table wrong still too

5" intake and it hasn't been retuned yet.

Re-calibrate MAF.
