Hey guys,
Im looking to go stage 2 but I have some questions that I hope some guys in the forum would have answers to. I have a 530i xdrive, I know it's a b48 but right now with the piggyback tune it's decently quick, I just naturally crave more power. I plan to get a CTS turbo high flow downpipe, so, for going stage 2, my questions are:
Do you guys recommend BM3 or MG flasher? I heard MG flasher has good low end torque but BM3 has more customizability. MG flasher advertises more hp for their stage 2, but it is much less known, does anybody have experience with it, or is BM3 superior?

For MG flasher, is XHP required? I saw someone say it will make you slower if you don't get XHP

Do I need any other bolt ons other than downpipe for stage 2? Should I get a bigger intercooler, or colder spark plugs, etc? For reference I have 53k miles.

Thank you guys.

Get BM3 with XHP. Regarding the mods for the b48. I have them all, larger turbo etc. I have never heard of a CTS turbo.
