Reconsidering the ECU issue...

One thing the XFi ECU may do to compensate for the different cam profile is adjust timing differently. Higher cylinder pressure would mean more chance of pinging under high load / high temps. So a guess is there may be less advance in the XFi ECU under those conditions.

Something to keep an eye on. Or an ear.
