What are the codes being thrown? And can you provide a datalog?

No codes are being thrown at all, that's the weird part. I attached a datalog with maf off first few min and then added maf towards the end.

So I looked at your datalog and the ECU is throwing couple of codes.

p2176
p003A
p2279
p0113
p0102
and then once you plug in the MAF:
p0114 - Intake Air Temperature Circuit Intermittent

So assuming that your turbo wastegate actuator arm is properly calibrated, there are no leaks in the intake system all the way to the throttle body, and your tune is properly set up with what mods you have... then I would start with the p0114. First thing I would do is check for any bent pins on the MAF connector. And second, is if you have someone with another Type R near you, borrow their MAF sensor, clear your codes, replace the borrowed one with yours and see if the code goes away. If not, you need to check for continuity between your MAF and ECU. See attachments.

Ignore the
