car had been tuned on eflex for roughly 2 months. within the last 2-3 weeks is when the first one played up. then it killed 3 within space of 1-2weeks. and i went to powerplay last weekend, and 1 injector i replaced on the friday, lasted me all weekend ( 900kms driving + 27psi ) then got home and it died the next day. then went to my tuner n got tune switched over 3 days ago.
