Make sure it's a "real" Walbro.
I don't see how the tune will affect the fuel pressure. The injectors may be an issue but you have to get the fuel pressure down to 58 psi at the fuel rail.
What are you running for fuel injectors? Again fuel injectors bought on-line can be a total mess not unlike FFR's.

Fuel injectors are stock chevy..in the fuel rail when I bought the engine tranny. this is the 6th LS swap I have done and I have never had this much trouble getting them to run right. Getting another filter tomorrow so we will see..
