Easiest injector upgrade for NA LS1?

Easiest injector upgrade for NA LS1?
I've done plenty of searching, but I'm still lost on what injectors to get. I'd like to get a solid ~400 hp out of my LS1 with H/C/I, and I figure I should upgrade the injectors now, while I have a tune that works I can mess with. I would like injectors that fit the LS1 rail/harness, have free data somewhere (or come with the correct data), and won't kill idle or emissions. Seems like I need around 35-40 lbs, I don't plan on FI or nitrous.
I think some of the Bosch ones fit, and I have found data for them as well, any more specific recommendations?

OK, did more searching. I guess these FIC injectors are redrills (say some people on the internet), and they don't necessarily plug and play with just an IFR change. The question is whether the ID injectors work 2.5 times better or not.
My last car had Megasquirt, so I'm pretty familiar with what it's like to have no injector data at all - it always had a little trouble on cold starts, then ran fine under closed loop and at WOT. Still, it would be nice to do things more righter this time around...

you have to put all the data in. And if you buy "new" injectors, they aren't re-drills. You can't simply JUST put the IFR in with any injector change....I mean you can...but its not right.
They have all the data, call them.

Thanks guys, seems like with correct data the FIC injectors work fine, agrees Google. This should be an adventure, the amount of controversy surrounding LS injector stuff is crazy.

Buick/ASA injectors are plentiful and cheap. HP repository has an ASA tune for the data
I know first hand it works. These are plug and play.
