Need you input on this log!

Running the Cobb OTS E30 map for the first time, car feels great.

After reviewing the log, it looks like I'm getting a bit of throttle closure and some slight timing correction across all cylinders. It looks like it's taking place when I hit full boost.

Is this just a boost overshoot and my wgdc needs to be adjusted? Or is there something else going on here?

Thank you in advance for the help!

Yep. Looks like boost overshoot in all three cases of TC in your log.

Think it's related to fueling, but I'm unsure. However, I have the same issue with the Cobb e30 OTS map. Logs look very similar to yours.
