I just had my car into the dealer for a quick look over and removed the Spider tuning Box and it felt as if i were driving a different car. The tuning box is incredible and a must have for any diesel owner. The pedal is so much more responsive and the torque is very impressive.
What did it do to your mileage? How long did it take to install/unintstall? Are there any computer memory issues available for the dealer? (E.g., can they know it was in there?)

The milage has gone up! This is a little different than traditional tuning. It reacts to how you are driving the car. It now takes me 5-10 minutes to install/uninstall. It is undetectable to the dealer because it is intercepted at the common rail. I cannot stress enough how much a difference this makes for me driving the R320 CDI.
