[Biturbos4] Best chip??

[Jason Cavaliere]

Hello everyone.

I think a lot of people here are like me.  I have an 00 S4 with 54k miles.
I want a very stealthy performer, and have a k&n intake filter and a milltek
exhaust.  I've prepped the BPVs and the TBB for a future chip.

The question is...what chip?  I wouldn't mind the 'peakiest' chip.

How does the chip change the sound??? A little bit more edge...
