STILL stumbling at ~2500 RPM.
So I have a 2000 WS6 and it has the stumble at about 2500 RPM. Just seems to have quite a dip in power there for some reason. I've changed plugs, wires, fuel filter, air filter, O2 sensors, cleaned the MAF, everything every thread I've seen has said to do. What could be left other than maybe the tune?

I have the same problem with mine. also changed all of those things as you.
does it happend while it changes gear? mine does it at around 50-60mph which is from 2nd to 3rd gear. if i go wot the stumble doesn't occur.
now what i have gathered with my aeroforce gauge is that when i get the hesitation i get some KR between 2-4 or so. in a few weeks im going to get a buddy scan it and possibly tune it for me with hptuners.
i'm leaning towards tuning but not sure why that would be the problem. havent added anything new to it.

Was the problem there before the EGR and AIR delete? As mentioned it would be a good idea to get it scanned.
I know you said it's at 2500rpm. Is that in every gear? Also does it do it at the same amount of throttle pressure? The reason I ask is it could possibly be the TPS. With the way the TPS works I have seen them have "dead" spots with in 0%-100% throttle input. They can get worn in spots, especially spots where you do your most driving because that's where the sensor is a majority of the time.
I hope that makes sense. Keep us updated.

Once again, where would I go to get it scanned?

Ever figure anything out OP?
I to have this exact problem, a slight hesitation right at 2500 rpm's in every gear and at any throttle pressure. my car still has all the air, no egr (01), and cats, just dumped after the i pipe so its stock.
Is the concensus still switch out the maf is my best bet?
