Stock 270cc injectors cannot do more than 200rwhp safely.
Whether that's 2psi or 15psi from your setup, that's the safe limit.
I'd bet your over that by a little bit with 7psi from a T25...you're just waiting for the day it blows due to a lean condition.
Same goes for you "Mr. Spool"...if it's an IHI T4 or bigger, you're pushing your luck.
Once the injectors go static, they can still supply fuel, but not enough for more than 200rwhp (at stock fuel pressure...).
