I'm thinking about just going with the Focus SVT pump, I can get that for right at $200 but a Motorcraft stock pump will run me a little over $400. If I could find the stock pump at a reasonable cost I would just do that and call it a day.

So yeller, your saying I may run rich for a while till the computer learns the new pump?
I doubt it'll be that far off. If you went with a 340 I'd say you might need adjustment in your tune.

I knew guys that dropped them in with no issues. Maybe it's different if you run two. I ran twin GT pumps on a stock FPDM with just a wire upgrade.
