hi,
got no joy from lexus Leeds, they said they wont change the injectors as they have had no instruction from Lexus GB there is a problem.
the service manager at lexus sheffield has told me the chap at lexus poole who started the changing of the injectors 'does not work for lexus anymore'
i really dont know what to do now, the remap got me an extra 1/2 mpg and 6th is more usable. those of you who have had the injectors changed.. how did you convince your dealer to do it???
