When joecar said "if you have the date", I think he meant "if you have the data". When you change injectors, if you have the data, then you really should change those other injector tables. Small pulse and voltage correction will probably be a bit different with your new injectors. This data 'should' come with the injectors... but in a lot of cases, it doesn't.
