trouble with MAF signal and Idling correctly on CTSV

[denmah]

dyno pull 5.hpl

crazy maf signal dancing all over on this cam 230/230 and headers CTSV

it has a K&N filter kit and fuel trims are fine at idle and cruise,

cleaned the maf and still having problems like this.

car runs good and makes good power 406whp but i would love to know why its banging around 40-60Lb min...

bad meter? something else?

also really having trouble getting this gen4 DBW car to idle teh way i want

hangs way too much or stalls easily ANY advice?

Your MAF Hz looks smooth... something weird must be happening with your MAF transfer.
