if I have a very strong station nearby while I'm using
OP1 on Tx & Rx and a very narrow DSP filter I may not
get the best function out of the filtering.
The AGC would see the wider bandwidth while the computer running PSK31
or whatever mode you are using would see the narrow bandwidth, so there
could be some pumping due to AGC depending on QRM/QRN.

That is correct. The DSP doesn't alter the frequencies.
