If it WASN'T happening before you went turbo, I would say to check your injector size, the FMU's operation, and the most basic component, the FCD or substitute.
Since this was happening before you went turbo, I would say it is likely an issue with your fuel pump, fuel filter, or injectors. What pump are you running? When was the last time you changed your fuel filters? Are you still running stock injectors? How old are they?
More info please..

You are not going to get any help if you ignore questions.

Do not bump a post by copying/pasting your last post.

It would be helpful if you provided information about your setup. Wideband? What AFR readings? Fuel pressures?
