I've noticed on other posts that folks are having lower flue temps than stove top. I'm the other way around. When my load starts to burn it is nothing for my flue temp to get 11-1200 and my stove top will top out at 700-725.My draft is only open about 10-15%. When it calms down and starts mellowing out it will be a flue temp of 800-900 with a stove top of 600. I had a new ss liner put in this year, but the stove doesn't act like there is too much draft. When it gets really going the flames tend to come toward the front of the stove, it has a good secondary burn . It holds a load good. I was able to restart this morning after 10 hours with just adding wood to a nice bed of hot coals. I t just seems that a lot of heat is going up that pipe
Is something backwards ?

Probe, I'm up about 19 inches. I put a load in about 40 min ago stove top about 625 and flue at 825

My flue always starts out higher than the cast iron stove top. When the fire is getting started and the air is wide open, the heat is going up and out. Once the fire is roaring and I reduce the intake air, the heat stays more in the stove and less goes out the flue. I use a probe on the flue and magnetic on the stove top.
Not sure why yours is different, unless your draft is really strong and is pulling the heat out. If this were true, though, you wouldn't be getting very long burn times and you'd have roaring flames for most of the burn.

Your confusing external and internal pipe temps. Your probe reads internal temps and they sound about right. The external temps on single wall pipe would be roughly half the internal temps.
That doesn't sound right unless this is with a full charge of wood being put on a very hot coal bed. The flue temps should be lower.
Has the stove always worked this way or is it a more recent occurrence? Have you checked gaskets?
Hope this is just a case of loading or the wood, but if the stove is a few years old and this just started happening, this thread may be important:

That's pretty much how my probe reads in relation to my stove top temps as well.
I have a second external magnetic thermometer only 3 inches above the stove top on the pipe and it doesn't say I'm getting close to overfiring the flue until the flue probe would hit about 1250 to 1300 I would guess. Since that magnetic is meant to be higher up on the pipe, I say that while the probe is consistent, I don't trust the scale.

Class 6 Pipe is only rated "safe-tested" up to 900ºF. I don't think I'd personally repeat those temps you've stated, too often.
Lower Flue temps than stove temps is common in my home set up. Frankly, I pay less attention to the stove temp THAN the flue temp.. Naturally the Flue temp will spike when new wood is introduced, and then I'll adjust the damper to make sure it doesn't exceed the Class 6 safety level.

Stove is less than a year old one of the new models. From what I am reading from other posts maybe the internal is supposed to be hotter. The pipe never comes close to getting red nor does it put off a lot of heat at the high temps. Gaskets are fine as I said it doesn't appear on the inside to over firing it's just that the flue temp is always about 200 degrees hotter even if the stove top is 400 the internal probe is at 600
