Trying to diagnose the X5m. I'm getting some sort of flutter and low boost codes and now misfires. Anyone heard this before...is it the wastegate not holding pressure? Or a vac leak somewhere?

Any ideas?
Bms stg1 / fabspeed exhaust mods
Now any WOT driving or harder acceleration cripples the car into limp (low power mode).
I'm sure I crapped out the plugs or coil..but that flutter is odd to me.
