What about it?

Put that stuff on and get it working. Then check your fuel trims to see if you are getting close to max fuel trims. It won't hurt you a bit.
Just changing the manifolds isn't going to magically increase your power enough to require injector changes. It is the CAMS and the ability to swallow more air near the redline RPM that makes the SVTs require a higher weight injector. Beleive me, the 19# injectors are way more than any stock SVT or modified 2.5L NA SVT needs anyway. The 19s are big enough for any normally modified NA 3L as well.
You only change injectors when at WOT you are seeing duty cycles on the injectors approaching 80% (which you wont) THEN you should upgrade the size.

NO TUNING is necessary by changing manifolds or anything in the intake tract. There is no freaking way you can gain that much airflow to require bigger injectors without at the least a cam change and/or a change in the max rpm that you can rev your car too.
That's not to say you won't gain some power with that stuff, but it won't be beyond the capability of the stock injection system and don't expect a miracle.
