Holy crap, that's some huge primaries!
I think if you put your injector sizes in the PFC, and then reduce the lag into negatives (start with like -0.4 or -0.5 or higher) until it idles ok, and reduce the primary percent to like 70%, you should be able to get to the dyno. My 850 primaries just made the whole cruise area really rich without reducing the main percent and idle was rich due to the lag, and my 1680's made my boost area really rich. Just be sure to turn your boost controller all the way down, and using your right foot try not to boost at all just to be safe. Like I say, if anything, you'll be rich, so if you limp to the dyno you should be fine.
You're going to want a wideband if you don't already have one. With that big of an injector change it's going to be impossible to get a good tune without a wideband and datalogit.

Gotcha. I can certainly associate with that. 
I've not heard of anyone running 1000 primaries, though I'm sure there's somebody out there doing it. You may have trouble getting a good idle with those, though. And I would expect it's going to take a hell of a fuel pump to support all that. Doesn't hurt to give it a try if you already have all the hardware though.
