I just picked up some 30lb injectors for $20. I figured since I'm about to do a cam swap, the stock 24lb injectors won't do. I was going to just swap them out, but figured that might cause some problems without a tune, like flooding my motor.

Obviously, I'm going to get a tune after the cam install, so should I just wait until then to put them in?

 

Yes. Wait. I recently did a head swap and added 42# inj's. was gonna drive it 45 minutes to the shop for tuning. When I called he told me to put the stockers back in and drive it easy and then reinstall at the shop. Said I could ruin my motor that way....but then again, 45lb's flow a shitton more than the ones you mentioned. We idled it with the 42's and it was sooooooooooo rich it wasn't funny.
