At what point should I replace injectors?
I have a set of headers, cam, CAI, exhaust, and tune right now on my LQ4. I will soon be replacing the heads, am I at the point that right now I should be thinking about replacing the injectors? If so should I just get 8.1 injectors or get some aftermarket injectors? Once I replace them, would the tune have to be changed? Thanks

Look at your software, it will tell you the duty cycle of your current injectors. Read the data the software is telling you and decide from there.
Yes, new injectors change the parameters of your tune and it would be wise to recognize those changes with your software. (I keep saying software because both EFI Live and HP Tuners can do what you're needing, and I'm not sure what you use.)

I would be willing to bet that what you have now is real close if not maxing them when your in the throttle. I would look for some injectors if i were you, pref 44's if ya can get them, or 60's if you ever plan on FI or Nitrous..
