Wow you print a lot faster than I do. Even if I’m printing functional parts, I like them to be visually pleasing. Don’t be scared to drop the speed settings a lot, the X1C and P1P/S are crazy efficient machines… they still have double and sometimes triple the speed of my Prusa mk3s+ with similar speed settings. For my outer walls I run >100mm/s to make the parts have little to no vfas. And on infill, I usually slow that down as well. ASA, but more specifically ABS prints can easily end up being poor quality because of infill. If you watch carefully, those infill patterns will print jagged and rough, sometimes causing the whole print to fail.
I usually run them at >=120mm/s. Just my observation
