Hi Torrie,
If one were to install these injectors, will the car still run correctly on the stock tune? I assume fuel trims would move negative on a stock tune and with a 30% higher flow it seems we could be close to the stock limit of +-30%
Also, I just read a comment from a Ford engineer about a "loss of resolution" when using higher volume injectors in the Eco 3.5 which is why they added PFI, to add volume while retaining resolution. When they talk about resolution, is this mainly concerning MPG's and the EPA, or driveability issues?
Has SCT been able to overcome these obstacles?
Any known tradeoffs running these in a DDer?
Have you had any tuning opportunities with them yet?

Custom tune is required for any injector change.
I would estimate the core is passing all federal emissions standards.
I am not aware of any obstacles.
There should not be but it still doesn't impact the HPFP limitations.
No but I know what's involved with it and discussed it with individuals that tested them on the 3.5L and 2.0L.
