Mark, did you manage to do any logging on the road? The reason I ask is I had my car dyno'd at eurospec 2000 and using ODBII hooked up to my CarPC the intake temps with my pop charger were massively over what they are on the road, at least 15C. We didnt try a run with the bonnet up, but certainly it was a lot hotter intake temps than I experience on the road. Would be interesting to hear if you did some on the road data logging.
