My 2015 435i auto is FBO with bootmod3. Can i upgrade my turbo to stage 2 without any other modifications (like fuel)?
Also since its my daily I try to keep it passing inspection (why i went with catted DP) should be no issues with emissions right?

If you dont want to upgrade your fueling then the PS2 is not for you.
3 ways to upgrade:
WMI (methanol injection running off a separate tank)
PI (port injection running off the pump fuel)
Other fuel pump
