    Default Flat spot issues please help

    my 2.0dti has got 2 real bad flatspots and when i put a tuning box on it has become more noticable. it happens at 2000RPM until 2350RPM then again at 3000RPM until 3250RPM would a boost pressure sensor do this or an air flow meter. i had it on the computer and on the occasions its been on the boost pressure sensor always comes up. but the mechanic told me the mass air flow meter is the only thing his computer doesnt read. Any replys would be greatly appreciated. Apologies for such a long thread
