Here is some logs at least. I don't have my car right now as my tuner is working on it but all your help is worth a lot!

Yep, Mike probably has this sniffed out…probably a bad HPFP

Could it be a physical leak? Since it's located in the valley maybe the leaking fuel would just end up in the oil returning to the pan.

The internal shaft seal can fail. This causes fuel to dump into the crankcase. If you continue to run it like this it can cause bearing degradation. This is typically caused from improper pump preload. Usually the pump is bottoming out. |

I am pretty sure we are dealing with a similar issue on my brothers C7 Z06 that has H/C 2650 with XDI +65 and LPE HPFP. All of a sudden, the idle fuel trims are -35. No matter what I do to the MAF or VE it doesn't change. Actually, it gets worse as I try to reduce fuel and honestly it should be lean.
