Nice you found the info on running 450s on a 2gnt.

If you're not going to run full standalone like one of the Megasquirt variants, or even a Hahn Portfueler, then the SFMU is your next best bet.

There's a plethora of info on this site for running SFMU setups. There are a couple write ups in the wiki section of this site as well. Just have to search.

When using the search function, try keywords like 'SFMU setup' etc, and where it says 'Search which fields?' change it to subject only. This will help you track down threads more specific to your keyword search.
