hmmm, he's clearly WOT in the log and throttle dip is a load spike. I guess it could be a spike from the plate closing, but doubt it. Always log foot position... it maybe in your log but you didn't graph it, just like rpm. Timing is still too low though and due to other factors then throttle.

Throw up a new graph with rpm as x and load, boost, timing, tps, accelerator as y

I just installed Cobb few days ago and want to log my runs as well, can someone please explain the correct way (or one mostly used for these runs) to launch, and also if you guys are using the DS mode or using the paddle shifters to shift yourself, and whats the max speed you guys hit or target for these runs and I'm guessing a straight road is required with traction control off. Thanks

i dont launch... i let it rolls out in 1st gear and then just pedal to the floor. it really depends on which gear you are logging in, for example mine is 1st to early 4th, by the end of 3rd you should be seeing 90+mph..
i usually use manual shift so i can control at which rpm i should shift.

Ah, now I see it...it looks good actually..the timing drop in 4th post shift is most likely to increasing IATs as by that time you're above 100F...add a small meth nozzle and you can run 93std and it'll all look perfect
