[40 Cylinders]

I am considering a tune w/o going the Femto route... I do see a number of choices but am curious about the Mosselman Itronic tune for the M3/4.. Has there already been a review on this that I can't find or has anyone tried this tune that could post their opinion ?
I was going to wait on CarBahn for the manual tune but they are slow to develop...

Femto would be the better choice, this is just a piggyback like a jb4 but with canbus integration, although it seems it just turns it off and on and nothing else. It installs just like a jb4 too on the map sensors and splices into a few ecu wires, might as well get a jb4, its user adjustable unlike this one.
