B6 1.8T vs 3.0
 

Hi people,

I had a B5 with a GIAC chip, but a couple of years ago, I sold it and picked up a TSX. However, I'm thinking of coming back to an A4, but this time a gray B6.

Just want to know pros and cons between a 1.8T and a 3.0.
Also would like to know performance wise between a 1.8T chipped vs 3.0.

All input, suggestions and recommendations will be appreciated.

TIA
