Well the DVDs were made years ago so if the data changed in 2013, I doubt he has that data in the DVDs. Unless he finally got his time machine up and running. I know you can get the gt 500 injectors for dirt cheap off of summit and other sites. So I would go with those since the data is readily available.

They have data on the ford racing parts website, but I can't find the data for the '13 GT500 injectors.

Ford data is in a completely different format, so it will need to be translated to GM formats. There is a spreadsheet on hptuners forum but I'm not a member so I couldn't download it. Could somone download it and attach it to this thread?

If you go here you can click on the injector and get the data. But I don't know if the gt500 injectors are listed here. Part Category - Ford Racing Performance Parts

Apparently the LS9 injector spray pattern is different, so the wall impact and transient settings need to be adjusted to use them with cathedral heads. Not sure how difficult or how necessary this is, but it does seem to be a concern for some.

Talked to a a buddy that runs the gt500 injectors he said he didnt have to get any data to get them working right and he has several cars that are low 10's and 9's with them that are daily drivers. Still would be nice to have all that info handy incase though

guys on the svt forums have made 750-780 on them on gas

Right. Most of the time you can tune around crappy data. But the validity of the other values in the tune depend on the accuracy of the values that define the physical properties of the mechanical components, such as injector flow data. My tuner and myself are convinced that the data for my current injectors is way off, making tuning a royal pain.
