2012 X5M Reduced Power(not typical suspects)

[Schmidty_]

2012 X5M Reduced power with no boost only code that will throw is 2C732B in the JB4 logger.
Injectors are index 11 replace in 2015.
Coils are the Delphi from N55/S55 motors.
Plugs are NGK 95706, new and gapped at .018.
Vacuum pump to solenoid to wastegate lines replaced with silicon.
PCV system routed through catch can and replaced with silicon hose and new PEX connections.
FP_H will only show to value of 4 at idle and cruising at 2, replaced both HPFPs. No change, look at FP_L and its only reading 23... Replace LPFP, same.

Any other ideas before this gets lit on fire?

Do you have Carly/foxwell scanner/INPA? Checking the code on there may be more helpful.

What does that code say? I'm not familiar with JB4.

Coils and crankcase vent lines were the culprits when I got the reduced power warnings.

Side note: Do you have pictures of your silicone vent lines and catch can set-up? And when you were getting boost did you see any improvement from that modification? Does it consume less oil?

Yup - I would check all the vacuum hoses that run across the top of the motor.

I'm in for some pictures of converting to the silicone lines etc. I want to do this as well. I'm trying to make my engine bay a little prettier in the process...

I once had one of those canisters come unplugged when I was tightening it back down after downpipe install and it put me in the reduced power/no boost mode as well...
