I don't mind beating a dead horse, because it has to be said: at 1.6ms there is no way in hell you should be hearing a delay or a chorused effect. At 8ms, I'm not hearing one, and I can play in realtime. At 8ms, there are some people who will notice the slight lag, but none of my 4 guitar-player friends (plus myself) have a problem with it, so this IS all coming from a guitar-player's perspective.
If your hardware's reporting your latency accurately, Amplitube is the only plug-in in your chain, and you don't have any high-latency plug-ins in the master channel (you HAVE checked the master channel and cleared it, I hope.
Try the demo for Green Machine II and see if you're still getting noticeable latency.
And make sure Amplitube doesn't have any delay/reverb/chorus effects enabled. <chuckle>
