I tested mine at idle once a long time ago. It was getting a little over 4 volts, like 4.3 if I remember right.

I have a buddy running a 450 on his 07 nnbs 4.8 frontmount 8psi and its running great. He did a couple modifications to make it fit.

Can you ask him to post up here and give a little more insight on any mods or problems he ran into?
