Default Injector size input for blown set-up

Hi there,
I'm new to the blown thing and need some recommendations on what injectors size to go with. I recently bought a set of PP heads/cam and Vortech SC with aftercooler. I would like to know what the best size of injector would be to go with? Could some one please help me out. I will also need a program when I get this thing all together, anyone have any good baselines for LS1 edit? Oh ya, it's for an A4 98 TA. Thank you.
Scott

What style heads and what cam...

42's should be ok if you don't plan on pushing too much boost.....

Cam is 221/224 558 558 114 I believe and the heads are stock LS1 PP. I plan on running 6-9lbs. boost and possibly upgrading the SC in the future. That won't be for quite a while though.

At a minimum you want 42's but you might want to look into 50's.
