X2!!! btw, do you have a shortram intake? If yes, your temps are absolutely normal after a WOT run.
yes sir i do i have a short ram intake aluminum rad with pusher fan. also no heat shield on oem headers. Couuld i be needing to adjust battery offset? i see it fluctuates.

it could be but that means that the alternator is not really good. because the stock battery tables for stock injectors are perfect

look at display and fix your altenator

From datalog, Battery Voltage fluctuates, The lowest and highest i seen is like 11.75 and highest 13.6 These are just the peaks, it might not be at one rpm 12.9-13.7 At idle. IS this normal? anyone have a map and datalog so i can see how my car sensors supposed to be?

how does the battery voltage look? messed up? also how much should the battery voltage read?

alternator may be bad under WOT voltage drops to 12V's How bad would this affect AFR?

Lots. battery voltage should be 14 or so

Bad ground would give spikes in the graphs. I dont see any so I dont think you suffer a bad ground.
