Freelander 1 TD4 Airflow readings

Hi all, went to use the FL last night & before I'd reversed off the drive the EML came on & was in limp mode. I plugged in my scanner which gave air flow fault. The MAF fitted is a Pierburg, along with the synergy 2a box. Luckily I kept the original Bosch MAF, which I fitted & has cured the fault but I was wondering if someone could look at the readings & let me know if they're within spec please ? First pic is with the fault & second with the Bosch refitted, thanks in advance.

Have a read, I have charted my standard MAF on a working 2002 TD4.

Guess your data is at tick over?

Yes, I forgot to mention that. I wasn't sure if I should stick to the Pierburg MAF with the synergy box.
