You flying -41 or -42. You increasing mass airflow by making the compressor work harder. Yes I've done a lot of work north.
By increasing more wf you increase itt and thus increase NG. And if your useing 3 blade props it's hard to reach max Tq before being temp limited even more so if you have -41.
You loste on your switches though. Amusing your talking about a b200
