Had a loss of performance ,which was related to a delay in the opening of turbo´s variable geometry,meaning that turbo boost or spool was delayed .
WIth vacuum gun,I checked for vaccum leaks and found that the turbo´s pressure converter (solenoid) was leaking and also from the vaccum pump to the whole system.
Replaced all vaccum pipes and replaced the pressure converter with the EGR pressure converter ,since I dont use it and it has same part # as the turbo converter.Also replaced the vacuum pipes on engine mounts!
Car as good as new after correcting a common issue .So ,hope this helps others with same symptons,as many have replaced turbos and the problem was the vacuum
