actually the MarkD tune works really well with 98 E39's(I had one with MarkD tune), it's the 99+ models that doesn't do much, also it works really well with automatics, another member here has a 97 540, he originally had the Dinan Stage 3 software & auto tranny software, he said it was shit, he than got a MarkD tune & said that MarkD tune was way better than the Dinan software & tranny software that Dinan offers.
