You should not listen to anyone telling you that larger injectors are needed. I would recommend getting a tune after an intake because the pipe diameter and MAF placement interfere with the air/fuel ratio of the stock tune. I was running pretty lean with my Stillen G3 intakes and am glad I got my car tuned since it makes more power now and it is running a safe AFR.

Dont listen on the Fuel injectors, If you go with a Full bolt-on set up such as Intake/Headers/Test Pipes/Exhaust, Yes get a tune you will be most likely running lean. Even if you decide to go with any combination of the three I would get a tune.
