If the position sensor value varies while you're keeping your foot in the same position, switching out the pedal assembly may help.
Thanks, it seems to do that. I feel like my foot is static on the pedal with slight pressure, and it's slowly coming up through the lower revs, when it bobbles for no reason. Probably would be good to get a log of the throttle response to the pedal action to see if there are any spikes or dropouts, but I think that would just bring me back to the pedal assembly anyway.

This isn't the car I'm supposed to be working on, I have the LS3 arriving next week for my C5 swap!
I just like cars.
