Question 1... are you on the throttle the entire way? I assume yes because pedal shows 100, but the logs are showing the throttle fluttering quite a bit.

Question 2... if you aren't coming off the throttle, then I am curious why the boost is so much less on the second run of the second log. I don't see boost target, so it is hard to say what the JB is requesting.

I don't think you are knocking for what it is worth. There are just some oddities. I am positive you could run more boost once you get the new DPs in there too. I would love to see a log running Map zero so we know what is normal with the N63R.
Base map log and graph would be great to see here. It would be most interesting to see what afrs are recorded with the factory map. The 13, 14, 14+ I see in those logs is really lean if I am reading the data correctly. We used stay in 12s but that was 15 yrs ago, maybe things have changed.

Keep in mind the 2nd graph has 2 logs

The graph and log that has 2 runs is map 2 and map 0 hence why it's showing lower boost.
I put both logs into 1 graph so you can compare side by side

I am on the throttle 100% of the time until right before redline

In the log look under map column to see which map I was running
