Torque Reduction During Shifts

Apologize in advance if there's already a thread on thisHas anyone experienced this w their M340? Specifically while shifting into 3rd gear. I've mentioned this a few times but have also heard some saying they've experienced the same. Apparently it happens in the Supra too.

1/2 gear is super rapid but sometimes when I go into third it's like a brief blip in torque/acel. Should note this is when I'm in sports + and shifter in manual or in sport trans setting.

Turning off DSC helps most of the time and short shifting seems to counter this as well. I can't quite place my finger on it, curious to hear if anybody has found a fix or solution to this?

I know getting a tune would likely help but I'm still not 100% sold and would like to know what my options are, if any. I thought my new PS4 tires would also help reduce this, but I still notice it occasionally when driving spiritedly.

^my car is Xdrive btw

It's like the car is reducing the boost/torque for a split second but it's not enough to call it an "issue". More of a curiosity. Also, during the 2 times I've launched this car, it didn't happen. Mostly notice when flooring it not from a dead stop

Wondering if anybody else is experiencing this w the Xdrive M340i's? It's not every time but def seems to be the tranny limiting the torque
