I run a 1.3 bar cap, so 15psi is definitely fine.

You can't regulate the current going through each relay using the relays, you have to change how the load is applied - if you're sure that the wires are going to the correct pins on the relay (which I'm not), you need to use relays rated for the huge current you're pulling.
