Well, with all of that potential fuel flow, your injectors will run at a low duty cycle and therefore propably last a long time.
There are some maps here:
http://www.hitman.hm/maps.htm . Nothing with the injector combnination that you have though. Maybe you could run without the extra two 1600's to start with.
Here's my map. I run 2 550's and 2 1600's.

There is also a 376 rwhp dyno run datalog. You MUST load my map to properly see the datalog.
The map will at least get your car started.
