Ian and Paul, I've recently kind of found the same and so have started running a 7.5 in 2wd, though on a big track like I expect this weekend to be a 6.5L will be going back in. I prefer to run the 'softer' motor and gear up as I find the motors much more tolerant on high gearing than I originally realised of the recomended overall rations suggest.
I also now run -15% throttle (and steering as it happens) curve, which I too have upped to 30% on occasion.
