[SOLVED] Low boost and slow spool

Checked for boost leaks now and nothing to be found... So last 2 options are the tune and the turbo. Gonna wait for the tune :)
 
alright he didnt want to take the risk to see if it fails cause the turbo is just acting weird so need to replace the turbo....
 
I already did a smoke test and a boost leak test and no result. I got ahold of Fux. A german tuner. He told me there is a bit of a clean up in ignition and timing and something with the AFR was not correct. He sees there is like a restrictor in the tune that may causes the slow spool and slow boost. He is adding boost and i got more boost. In the negative boost it spools up REALLY fast!! like 1 tap on the gas and im boosting. Above the that it seems its still a bit struggling... to be continued
