Gen V Engine swap info

[vannatta20]

Going on my experience ( 6 gen v swaps) they all used 57 psi fuel pressure with no issues. Fuel trims are dead on and wot is fine. If this will not work I should have experienced some issues. By all means use a fpcm I just have not had the need as of yet. I was surprised since GM says 72 psi needs to be used. So far no issues at 57 psi. There are many different ways to do this I am just letting people know what is working so far.
