CSL SMG CODING inquiry

Hey Guys,

So i just got a dyno tune for my car, which included the CSL ECU and CSL SMG module tunes. The car drives great, but when i down shift (while braking), the car engine brakes immediately... no blip whatsoever. I almost get tossed into the windshield, that how hard the engine braking is. In S3, it seemscto blip correctly, but anything above that, its a violent jerk forward.

Has anyone else experienced this? Does the ECU have to adapt?

Thanks in advance!
