Tuning and tweaking will continue next summer when same engine will be put to the Audi A8. We will try some different setups to learn more.
25 tunes? Sounds like you have a lot of experience. 10% is quite an improvement. What kind of testing did you do? How much are you into the tuner/software and dyno time??

Also, is there more potential tuning a turbo diesel versus tuning a naturally aspirated gasoline motor?

Sorry for the barrage of questions...I am curious.
