If I recall you have a predator - take to a local shop assoicate with diablo and have them stick a snifer up the tail pipe and dyno tune the vehicle.
He'll dial it in. Additionally, he can get a custom tune from diablo should you require it.

You will be provide with print out of the first and last run showing the imnprovements made and you'll see where your power band is at.

It will money well spent. Once surpass the hand tuner capabilities with mods go to the same shop sarge did...

You'll need to move on... as far as capabilities of the software used to take advantage of mods...

Well stock cam makes peak power @ like 5600rpm. I would say it is nosing way over and done by 5900. You can rev it to 6000 but you are not going to gain any performance. I think A4 cars max TQ on stockers is right around 4000-4100rpm.

So when your asking how high you can go you are asking about changing the rev limiter or shift points?
