I would check the BOV and perhaps a possible boost leak. Good luck!

+1 on the boost leak test.Check your intercooler piping,pcv valve,throttle body shaft seals etc........

In the last 2 logs you are pulling timing from knock. Log 3 had a max of 6.7* ret. I would drop your coolant CEL to something helpful like 220* instead of the 245* (which is way too late) that it's set at.

Why do you have your intake temperature locked?
Your open loop tables are ass backwards. Octane map appears to show the min table on the max and vise versa. Your displayed min table looks a bit funky as well.

Your airflow still needs worked on as your wideband doesn't match up with your AFREst. You are at times a full 2 points off from each reading. The first log has a low spot showing 9.6:1 (wideband) 12.3:1 (AFREst). You need to go and fix all of that so both match during WOT.

Other than those, I personally don't see too much going on from the available logs. Can you isolate the exact moment where it's causing the issue to make it more readable?

Please fully fill out your profile as another issue I see is, are you using 600cc injectors or is that just how you have your fuel calculated in Link? Do you have a larger pump or an AFPR to verify fuel pressure?

I am currently running r/c 750cc injectors. Intake temp is locked because I do not have a A.I.T sensor. During the pulls I was using the min octane maps.Ii have link set up for dual maps. I will drop the coolant temp CEL A.S.A.P . The car still has the stock fuel pump hot wired. The fuel pressure regulator it still stock also

Added new log in first post its a 3rd gear pull. With a lot of knock max 13.0 deg

sounds like a bad BOV or a boost leak.

You need to get your fuel set up before worrying about the other stuff at the moment. Get you AFR in check and post up an idle log at operating temps to see how it looks.
