Holy Throttle Closures

Here are a few more 3rd gear pulls. Sorry I couldn't get quite to redline but the conditions didn't allow for that kind of speed. Anyway, My main concern is repeated throttle closures due to overshooting requested boost. I keep seeing it consistently around 2500 to 2700 rpm. Is this a concern, and if so is there any way to correct this? How do the other parameters look? It still seems like AFR is a bit lean on spool up where it jumps as high as 16 AFR right when I go WOT. It does drop quickly to 12.2 AFR. Again, this is stage 1 aggressive v. 4.01 ST. Thanks guys!
