I'm having a hard time getting realistic offset data for this injector. This is for a 4V 4cyl but you V8 guys probably have a lot more experience using Dsteck's ford to GM conversion sheet in Excel. Here are the injectors.

This is the offset data for MAP and IGN voltage I am getting using Dsteck's conversion chart. It seems really off to me in the higher ranges. Am I really off base here?
