Thread: MAF readings (feel lack of power under 2000rpm)

As in title, I feel my car a bit weak under 2000rpm. Basically all Nanocom data seems to be ok, MAF between 50-600, other values within spec as well.
Yesterday I thought I give a try for the old MAF and put it back. Car seemed to be better under 2000rpm. I have evaluated both Nanocom datas and here what I have found. The old Siemens MAF seems better under 2000rpm as it starts to give bigger values earlier and also goes higher in some cases. Maybe it means nothing but would be good to compare them with data from a new genuine MAF. Does anyone of you has such data?
