If I were to go do a fourth gear pull right now, what should I log?

Your logs look good, I wouldn't change much if anything at all.

If you have a way to log boost, RPM, A/F, & TPS you decrease your spoolup time by alot. I got my stocker to spool stupidly fast using the LM-1 w/RPM converter. I plan to do the same thing with the 35r.

Yes, it maximizes the boost because the engine is cannot run through the rpm range as quickly. More boost will give more load.

I guess it depends on what you want to see/accomplish. For my first logs, I was mainly interested in observing knock sum, ign adv, and Octane during WOT vs rpm/load. I was also curious about coolant temp and air temp. Would have been nice to be able to log EGT, but the Evo doesn't have one of those built-in. :-)

Do you have Data.xml file with updated air temp and coolant temp formulas? Just asking because your air temp values seemed a bit high.

Those logs look pretty good. I would throw in a 50/50 mix of pump/race gas and log some more runs to see if you still get knock counts around 4000 rpm. If you do, then the knock sensor is picking up engine noise and not knock in that area, and you don't really have anything to worry about. If the knock sums go away, then maybe think about pulling out some timing between 3750 and 4250 RPM.

Tom - do a 3rd gear pull from 3k-ish to redline as suggested. I'll do a couple today and post them tomorrow. My setup is very close to yours but I think I run a little less timing at initial max boost.

First is a third gear pull, then a fourth gear pull. They have a space inbetween.
91 octane, around 90 degrees out.

Its a shortcoming of logging with the ECU.. the output is clipped at 1603hz

Hence the reason why load is calculated using values that aren't clipped.
