Here are some numbers that I have heard:
264 rwhp and 314 rwtq (with 3000 miles)
Has anyone else dyno tested their new Hemi?

I have seen as high as 288 mentioned, but I understand there is difficulty in getting a good dyno. the speed limiter kicks in at 5400 rpm in 3rd gear (108 mph).

That is a good point. The dyno graphs that I have
seen show a peak HP reading around 4400, and it
is claimed by Dodge the peak HP sits around 5400.
So the 260-rwhp numbers are not yet at the peak.
MPP will sell PCMs like mad when the release them!

The Kenne Bell hemi ram pulled 281 rwhp before mods.

Do you have a 1500 automatic version? You may run into some trouble when the speed limiter kicks in early. Many owners were complaining of only 240-250 at the wheel. When it should be around 280ish.

Any numbers?
I found out the hard way on the first dyno run of the Dakota 4.7 with beta runs with mods when the speed limiter kicked in at 97MPH.
