You should start it with whatever injectors it is tuned for. In fact, an injector change should not be done until you are with the tuner.

+1. I would not try to start it if you have changed the injector size.

I'd like to know this as well. Is replacing the stock injectors a must when doing a heads/cam swap? I'm about to do mine and hadn't planned on injectors.

yea put the stock injectors back on there or have your tuner calibrate the computer for the larger injectors. The last thing you want to do is kill your rings because of too much fuel and you will do that.

To get it to idle better i would adjust that screw on your throttle body.

I drove to the tuners with stock injectors and changed when I got there. He did an initial tune for the restart with larger injectors. I agree with all above.

Don't start it with untuned injectors. If anything leave the stock ones in and swap them when you get it tuned. It will be okay to drive a bit untuned otherwise. You might have to help it stay idling though. But don't run it with the new injectors until you get it tuned unless you plan on putting rings in it.

Exactly, you dont want to start an engine without the right injector scaling in the computer.
