Unhappy Boost Cut W/ No CEL's HELPPPP!! - 10-05-2020, 06:48 PM

Hello! I am new please bare with me.

Currently my car is mostly stock.

Fuel injector(s) replaced - 33k
Engine replaced - 33k
Cylinder head gasket(s) replaced - 33k
Transmission replaced - 80k

I have stock turbos, ***-less down *****, dual cone intakes, no mufflers, with "stock" MHD tune.

I have a few "shadow" codes and 1 active code that showed up and left.

Active: (but gone now after resetting DME and forcing boost cut)
2AAF - Fuel Pump, plausibility

Shadow:
29F4 - Catalytic Converter conversion
29F5 - Catalytic Converter conversion
2FCA - Fuel high Pressure
2FDA - Crankshaft Sensor, Signal: Missing

Upon start up from time to time I will have rough idle for 5-10 seconds. I have attached data logs from MHD. I plan to have a walnut blast done in the next 2 weeks and plan to replace the Crankshaft Sensor.

Any help would be highly appreciated.

THANKS!!
Nate

BUMP

I swapped out the LPFP sensor and HPFP sensor same codes. 2AAF never came back but I do have a slightly longer crank than most. (pressure is held prior to engine shut down) Crank position sensor is next. Same symptoms...
