I don't believe Gavin ever ran it without the extra 2 injectors, but if I had to guess, I don't think it would run lean with the 6 stockers with the right tuning (at his current output level), but they'd probably be near max duty cycle and they wouldn't last long.
From what Gavin has said, he's using a pretty advanced piggy back. I don't know enough about the situation or piggy backs in general to comment though.
