Hell yeah, I don't want to make a single change to this amazing vehicle.

Very satisfied with stock, but I may make a few slight changes (e.g. tint, tires, clearbra).

Stock sucks - can't wait to make significant alterations to this car (warranty be damned).

Satisfied with stock? Or must you mod in some way?

stock K03 B5 S4 turbos will run 18-19 psi at 3500 RPM, but taper to 12.5 to 13 psi at redline. It is still an average gain of ~60WHP accross the RPM powerband from stock tuning, very noticeable.
