Accelerating RPM Drop

So Ive always noticed this under light acceleration since I was stock I think but when I'm accelerating in 3rd gear around 2.5k RPMs me needle drops and you can hear it too. I felt like this went away when I got my steeda CAI but now I'm noticing it again after I've had me mpt tune on for a week and it seems like more of a drop. Does anyone know if this is the drop in the torque curve. Anyone else have this? I'll try to link a video

Did you try the fuse 47 pull? That fixed this for me

I've done it before but It was during a time I wasn't worrying about this so I might have to try it again.

Definitely try it. I "think" it's your adaptive shifting kicking in. Not sure, that's just my guess.

It has nothing to do with the shifting tho

The rpm drop is due to the torque convertor locking up. It happens shortly after shifting into 3rd gear.
I have a tune and fuse 47 relay installed and I can still feel the torque convertor lock up.
