520d/E39 se tureaza greu

Am un 520d, tocmai i-am schimbat blocul motor+chiulasa. Intampin urmatoarele probleme:

dimineata porneste destul de greu, se invarte de 2-3 ori, tin apasata pedala de acceleratie la fund in momentul in care pornesc motorul, si raspunde de abia dupa vreo 5 secunde. De altfel, dupa ce am pornit, are o latenta in acceleratie, se tureaza greoi... de abia dupa 2mii de ture devine suficient de responsiva. Ce poate fi ? Pe tester, i-a dat cantitatea de aer vreo 540 din 610g cat trebuie sa aiba, deci debitmetrul am inteles ca nu este dus. Si EGR-ul am inteles ca functioneaza destul de bine. Poate fi din soft ? Sa fie vreo pompa ce nu alimenteaza corect ? Pe tester nu imi da nimic. Pompa de injectie e bine pusa pe punct, consumul afisat de bord e mai mare ca inainte, de altfel am senzatia ca nici acul de la combustibil nu afiseaza prea corect. CE SA FAC?

Mersi anticipat
