Unmodified OEM injectors are a great choice but the issue is that the injector data for them is proprietary to the manufacture that spec'd them from the Injector company. They can not share the data so the only other choice you have is dubious internet supplied, borrowing the data from various EMS repositories (that is a great "hack"), develop the data on your own (horrible to do, 10/10 don't recommend), or send the injectors out to someone that has the correct equipment to do so.

In my case I have someone I work with that invested in a Greg Banish designed (Calibrated Success) injector testing machine to output all the data. After going through its test sequence It will supply you with ecu specific injector latency, non linear pulse width multipliers, and flow for various voltages and pressures.

My thought process was that an easy to replace in the future (10, 20 years down the line), and an OEM level injector originally designed for essentially the same engine design was a smart move.

When in comes to needing a lot of injector my absolute go to is Injector Dynamics. Paul at ID is as brilliant as they come and supplies literally the best injector data possible. They have tested their injectors with a few choices of ECU's and supply EMS specific data as not all drivers inside the EMS units operate exactly the same so latency will be different between a Motec and a Haltech as an example.

One note about the Maxxecu data, their testing is done with e85 so the flow numbers will be a little different if you are using gasoline or gasoline with smaller amounts of ethonal.
I didn't realize they tested with E85, thanks. I really should swap them out and go with ID injectors with good data. It's bone stock 3.0 and although I didn't do anything to get more power, it certainly feels quicker particularly once I get past 4000RPM or so. I need to bring it to you.
