Mine had up to 20% errors in the mid ranges. It turned out a someone decent looking curve in the end, and the AFR is perfect now. Did anyone else get such a large error?

Also, do you guys smooth out the table or should I leave it like it is?

 

i took mine off..didnt think my truck needed it that bad and i didnt wanna mess with calibrating it and all that stuff

 

Its a little choppy but it should be fine, that spike around 9k hz is most likely where you hit boost most often. I remember when I had a MAf my did that slightly around 8k Hz.
