If you're familiar with GEN4 stuff, the condition you're describing is typical of BRAF being too high, throttle follower being goobered with by someone who doesn't know what they're doing, etc. It's an idle flare after a downshift. That being said, I can't tell you there's a silver bullet fix for it in this. It is most likely a combination of things all revolving around idle torque control.
All that being said if it came to me to fix this problem a bunch of it would need put back to stock and start by dialing in the VVE and VVT.
