Hi y’all. Ive got a 08 b7 a4 6mt that started having this issue Thursday (11/15/2022) morning. Vehical had little to mo throttle response(while in neutral) to the first 30% of thr throttle pedal. While up shifting, for example from 2nd(2500 rpm’s) to 3rd the rpm’s will increase with it in neutral and no load on ending. Then they will slowly decrease. Before this started I had instant throttle response, cruise control functions working and no rev hang at all. Rpm’s would drop instantly when it went into neutral. It builds boost instantly. There is no clutch slippage anywhere. No dash lights and with a obd2 reader I scanned the entire car and there were no codes related to this ( only radio codes bc aftermarket unit)
What could be the issue?

Diag done:
Cleaned MAF
Throttle body relearn
Install of stock air box
Cleaned out catch can
Install of new clutch pedal position sensor
Cleaned out all the intake pipings

Plz lmk what it could be.
