Have you tried running a higher air setting? I generally find I get lower temps with more primary air, typical overnight for me is 40 - 60% setting. The STT is hotter but the cat peaks are shorter.

Running with really low airflows gives you a longer, smokier primary burn and it creates a lot of fuel for the cat. So it effectively shifts the combustion load from the primary to the cat and leads to higher secondary temps for longer and low STT's. When I run low airflows my glass blacks out and if I open the griddle a crack I get a huge cloud of smoke out....

I found things are more controllable with higher airflows, but my metal cat is also peaking at 1550 - 1600 on a full load.

Yes, this year has all been with an air setting greater than 50%. It has been frustrating.

I have been running hotter with higher STT's than normal to see how it would go.
