Actually, yes the Autocal can - if you enable the 'Advanced Menu'. It has the same 'Read GPM Injector', 'Write GPM Injector', 'Read ECM Injector' and 'Write ECM Injector' as the V2.
Yes, it's possible an injector had bend replaced and the new flow rate not properly entered, but that being the case, why did it only pop up after the tune? Either way, when you get a code that is likely or definitely related to an injector flow rate issue, the first and easiest thing to suggest is reading the GPM injector values and writing that to the ECM.
