M235i Problem Stage 2 93 OCT

Been having problems with my M235i since I bought it a couple of months ago, I purchased it with 27K miles. Did FBO including new plugs
List:
NGK 1 Step Colder Spark Plugs
GFB Diverter Valve
Dinan Carbon Fiber Intake
VRSF 5" Intercooler
VRSF Catless Downpipe
VRSF Turbo inlet
VRSF Charge Pipe
FTP Boost Pipe
AFE Mach Force XP Axel Back Exhaust

Car is running a brand new MAF sensor was running worse before this and I had CEL on for codes relating to it.

Problem I am having is when the car is tuned usually around 5.5K+ RPM/Shift point the car starts to choke hard. In generally the car is loosing a good amount of power. HPFP is missing target in logs and I'm not too educated on cars, but seems to be running leaner than it should. Car has minor vibrations maybe 50% of the time on startup that continue anytime when stopped and may go away after driving a while. I have videos showing my issues so hopefully you can listen and have a better idea.
