Two days ago, at the last PCA skills day event, my afternoon mentor (I'm an instructor candidate for PCA skills days) gave me some tips for autox. He said that as you approach a cone to go around it, blip the throttle a little to rotate the back, then to get ready for the next cone, lift off a little to improve turn-in.. I thought that was a good advise, hope it helps..
Also, try left foot braking.
