Fun pedal, Few doors
Yah, I figured that would be in the realm of ProEFI or similar.You can’t really. Tested many years ago and it doesn’t work in minor adjustments and causes issues with larger ones.
If you want real individual cyl control run aftermarket injection.
But back to the original question: if a couple of your injectors tested say 3% higher flow rate you could put those on 7&8 just for a little peace of mind…
