The Stage 1 tune did not work very well with the N63TU and S63TU engines so that's not the X5M. I can't say for sure but it is my understanding that all users were contacted and the tune was remapped or replaced free of charge because that's how Terry works. The functional version for all N63/S63 engines including TU variants is for sale: http://www.burgertuning.com/N63_Jb_B...nce_Tuner.html

Stage 2 for the N63/S63 is out in beta now with the TU variants coming not far behind. I know three or four folks running it on various FB groups and it looks solid.
