2011 CTS-V: VVE pulling -10- -24 fuel across the board
Just started tuning my car after it's last round of mods. I haven't really used HPTuners since 2.24 on a P59 PCM, so I'm a bit out of practice. I went through and got the car into SD just fine, but I'm wondering about a couple of things. Mods are below. The red texts denotes what was changed.

1. After doing some logging with the VE vs LTFT+STFT with LTFT on, I noticed that my car is pulling a MASSIVE amount of fuel. So I made an adjustment and used the "paste special ->Multiply by 1/2 %, correlated values, and loaded it to the car. I've kept throttle inputs to smooth, steady to avoid transient fueling mumbo jumbo. I don't understand as to why it is over fueling so much, unless that's just how bad the tune was before (didn't log it before, as my buddy had my HPTuners for like 6 mo, I know, my fault). It was tuned for the previous rounds of mods, but ran extremely rich (black smoke rich) on WOT, so I don't know how good the tune actually was.
I have attached the logs, channel layout, and graphs.

2. I'm having issues getting my EQ ratio error to show up on the graph. I haven't the slightest idea as to why it's not working. I'm thinking its because EQ ratio error function isn't pulling the values from the NTK AFRM that I have hooked up, as it doesn't have it loaded as a native lambda sensor.
