I took delivery of a Bluefin today for my S3.
10 out of 10 for ease of use by the way!
I then went for a drive a to be honest I dont really notice a huge difference! Was I maybe expecting too much? I have read of other people saying it completely transforms the car! It has made the DV valve a bit louder and the turbo makes a more pronounced noise in the car.
If it makes a difference, I have only done about 10miles since installing it, will it get any better as the ECU adjusts??Heres hoping!
