I'm getting ready to add a fuel flow system and the two choices seem like the Shadin Digiflow and the JPI 450M. I've read the manuals for both and the Shadin has the advantage of being STC'd as a replacement for the factory fuel flow gauge.

But the JPI has the advantage that it can show fuel consumed per engine instead of just as a total, and that it's less than half price. It's tempting to save $1800 and go with the JPI and just leave in the factory fuel flow gauge.

JPI does have an STC for the skymaster as an advisory gauge.

Seems like JPI may be my choice, am I missing something?
