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

How is jb4 not in the same league?
I would buy a burger tune any day over this, based on my experience with an n55 jb3.
