I bought a set of those skinny all-red 36# injectors, aka "SVO injectors" for my LS1 Miata in preparation for future upgrades. It's a stock engine from a 2000 Camaro. For some reason, the injectors just don't seem to flow what they should, I had to drop the IFR table a bit to get anything other than +25% fuel trims. Stock injectors ran fine, other than the fact that one of them was leaking.
I used the spreadsheet here for the data, double checking the FRPP data matches what was entered already:

Here is my current tune, with a "fudged" IFR table, offset/short pulse from that spreadsheet and stock everything else:

And a datalog running on that tune, with rich-but-not-insane LTFTs:
drivefromwork.hpl
I checked fuel pressure, and it measured "60 PSI" on an autozone gauge. Close enough I would think. Other than the data just being plain wrong, what else could cause flow to not match what it should be?
