Turner is willing to do $1500 for the Hartge tune when i emailed them. Still a lot of money for a piggyback system but looks like the only option at this point.

You can NOT compare JB to Hartge. Hartge is in a completely different league as a Bmw tuner in Europe

What impact do these piggyback tunes have on fuel efficiency and the different drive modes?
