Just noticed when on ExtremePSI's site, that they have a new release for the Walbro 450 but with a higher pressure releaf. Interesting, any thoughts?

What's your question?
The higher pressure relief is for cases where you're running high boost. If your not it's not required but won't hurt.
Remember there are pressure drops in the fuel lines so if you're running 43.5 psi base and want to run 25+psi boost you need a higher relief valve so it doesn't open and kill the flow rate.
