Unfortunately, the tuners will most likely charge twice that amount when they see the M badge. They will claim that they need to be compensated for all the R&D..and all the other bull.. Exactly what they say when it comes to the MB V12TT...they charge astronomical prices (i.e. RENNtech $5,800) because they know that it is such a huge increase in hp that they will not be selling too many other performance products for that application....so nail the consumer while they can.
At the same time, hopefully the relative ease at increasing horsepower through software applications will inspire some healthy competition among a number of tuners, thereby driving the price down. The will be some risk, of course, in getting work done by new and yet-unestablished vendors.
