The MAF is only a month old and a genuine Bosch one, if the MAF was faulty wouldn't it show up in other areas and not just at 5400rpm because once passed 5600 it pull clean and hard again everytime
If it is brand new Bosch and clean it is probably ok. A flat spot in the rpm range while running fine everywhere else is a common symptom of a failing MAF. It rarely affects the entire upper range unless it is completely fouled.
