Does it make the engine rougher under normal driving for the sake of increased performance?
Pros & cons please from anyone in-the-know.

1) Yes, very worth it!!
Well you already have a very good engine, but you can gain a lot.
2) Very significant!
3) No, mpg stays the same as long as you don't use the extra power. It's a fair compromise. My car still do the same mpg at same speed.
4) Rougher??! Well my wheel have some dificult staying in the ground...
No. To be honest I was expecting same kind bad behaviour, but the engine keeps it's linearity.
I made an upgrade to my 2.0TDI and the car became (much) 'lighter', stronger and much more usable. I can now get to 235 km/h (measured with a GPS device; the car indicates about 250Km/h) but only because the cars is already 'cutting' power from engine (red line, at about 4700 rpm)
