I was already running 65lb injectors long before I put the turbo on. I just happened to get a good deal on them a few years back.

15psi is going to require at least the 42.5lb injectors, and preferably 65's. I have seen a max of 75% duty cycles on the 65's at 15psi, but that was running very rich in the mid 10's AFR.
