Please check my gt35r on 91oct log
I'm getting a hang of it now. Car is running good no more idle problem, very good idle and response, no p0300 or any code. I hope when it's close to perfect I can start helping some members that needed help.
I did a log from stop, full throttle through 1st, 2nd and 3rd gears. It feels good with minimal knock sum. Please tell me if the fuel trims look ok (if not give me some suggestion) and is there anything I can do to improve the power. Thanks.
Note: Boost peaked at 22.1

You're logging too much at once and not getting enough data points. For example there are only 8 data points between 4800 and 7500RPM.
Fuel Trims are tuned at idle and at cruising speeds, not WOT runs. As you can see, your fuel trims did not change the entire time.
Reduce your log to just: RPM, TPS, AFR, Timing, Knock, 2ByteLoad, OctaneFlag
Then do single gear pulls, such as 3rd gear, 3000RPM to 8000RPM.

You also need to post a log of a full pull in 1 gear.. not 1st through 3rd..
Start in 3rd or 4th gear at 2000 rpms and go WOT to redline. All the high load areas that are likely to knock - boost transition areas 2500-4000rpms in 3rd and 4th are not in the logs because your already above that rpm when you shift into 3rd.

I never log WOT less than 3000 rpm because the car is never driven in those conditions. Timing is set low in that area just in case I go there on accident an d boost would be about 32+psi if I did. It's not the knock I'm afraid of - thats under control - it's the force on the rod bearings that keeps me from going there, let alone needing to drive in those conditions in the first place.
A 3300rpm to redline log in 3rd and 2nd, then a run through the gears is about all I need.

good point when you shift into the next gear its not going to drop to 2k LOL but i too set my timing low there just incase LOL. but i usually do:
-3k 3rd gear pull to redline get everything dail in
-after everything is good do a 3rd and 4th gear pull since 4th has a higher load make sure everything is still good
-finally I simulate like I am @ the strip log that from a dig to 4th @ redline. we have some back road back here LOL
