    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 ?

    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?
