2.0t stutter 3rd gear 4k rpm ??

[Marrow]

Hi guys car has developed a strange stutter/cough at 4krpm but only in 3rd gear WOT any ideas car runs fine other than that no CELs ?
Car is mapped with intake. Pcv replaced & rev d diverter valve fitted.
Could it possibly be fuel starvation due to map ?

Possible could be fuel pump. Best get some logging done to see whats happening

Do you think i should be worried ?

sounds like fueling, a pump should sort it. Has your work been done recently or has the mapping etc. been in place for a while?
