I have never tuned an Anniversary car as I don't see what the difference is in performance from a normal car. Your tune changed my mind. this has so much turn in grip and braking ability that I would rate this as probably the most fun you can have in a 600pp race car. It is quick, and as you do more laps you just want to drive it harder and it doesn't bite back. This is such a good tune. I haven't tested it against 600pp tunes for the normal HSV, but I have a feeling that this one will excel purely on cornering grip.
Great tune GR65 - the best!
