What can I do to a B7 4.2 V8 auto box engine?

Hi

Just wondering what options I have for increasing the power on a B7 S4 semi auto box convertible. 4.2 V8 engine.

I have heard my options are limited, is this true?

Thanks

Yes that's it. Tiptronic auto I meant. I never know what to call it.

Basically not the manual in B7 S4 form.

So remapping isn't worth the cost as gains very small?

Thanks for the advice guys, maybe the exhaust is the way to go
