Hey you guys I was having some issues with STFT hitting 34 several times which made me concerned. I received codes : 29E0 & 29E1


My LTFT fuel trims are kinda high around 25%(while cruising) giving me codes “Mixture Control” on both banks. To my understanding I am running lean. It’s weird because once I step on it it’s closer to “0” which is good right? 🤔

I’m running stage 2+ can you guys tell me if anything looks abnormal on both these logs.
Thx

Recently installed stage 2 LPFP & ARM 1k intercooler

I had these same codes and yes a Positive (+) in terms of fuel trims means "Lean Condition"
LTFT's going to "0" under WOT is normal.
The logs you posted look ok though
I've replaced all vac lines, clean MAP sensor, replaced o2's and replaced injectors to index 12 in that order. The injectors fixed the issue.
