How much hp will stock '02 injectors support? All my mods are in my sig. I'm going to set an appointment for a dyno tune after I reinstall the tranny this weekend. I hope to have about 420hp at the wheels. 
Which comes out to 480 at the crank. How much can stock injectors handle?

Not sure, but I guessing my RWHP to be around 400, with an A4, based off the times, 11.791 @ 113mph. I was running 02SS inj and IDC was over 100% at only 6300rpms, my shifts are 6950rpms. Might want to go ahead and try it, I am sure they'll push the fuel, but not recommended.

Do you think my stockers will get by for a couple months of weekend driving before I re-dyno it with larger squirtguns? Redline will be 6,800rpm. Any comments?

02 28.8 lbs injectors @ 58psi will handle up to 450 rwhp.
Just remember that it is better to run your injectors at ~80% max duty cycle.
When you go to tune, you'll find out what your cycle is and base your decision on that.
IMO you will not need injectors.
A better mod would be to get an adjustable fuel regulator at the rail and that way you can maintain your pressure high at WOT and not affect the injectors. Racetronix has them/
