MAF - Which one? Bosch or Low Gain Pierburg with Digimafam?

Hi,

Today i noticed my Bosch MAF values on Scangauge are really low at idle.

I remember to see values around 2x m/s and now it´s showing 11-12 m/s. I usually check those value when the engine was cold and today i check them when the engine was hot but i think it will make no difference. However i´ll check again tomorrow with the engine cold.

I have a Digimafam and i remember it made some nice difference in the past when i installed it with the Bosch MAF (even when it was good) but now it seems to make little to no difference regarding those values and driveability. It seems to increase 1/2 m/s at idle at most.

I unplugged the MAF and the car seems quicker below 2000RPM, so i guess my MAF must be almost shot.

Tomorrow i´ll try to clean it up but i have not much hope.

So, the question is, which MAF should i get? Original Bosch or Low Gain Pierburg?

Low Gain Pierburg seems a good option since i already have a Digimafam and SDi injectors but i´m afraid the power delivered by Low Gain Pierburg + Digimaf will be lower than a original Bosch. I think i remember saw somewhere values around 10 m/s at idle with this combo? Will Pierburg + Digimafam really match original Bosch performance?

Whats your opinion? Which MAF should i go? Original Bosch (if you know anywhere i can buy it cheaper let me know please) or Low Gain Pierburg?
