Default Injectors size?

Installing Super ram, 52 mm BBK throttle body and 1.7 roller rockers. Can I use my stock injectors?

Wondering if the ECM will need a retune.

I have done it, yes you can stick with stock injectors. You're only adding an intake change.

However, it will have dead spots and surges in the power band. It would be better with a tune, but it will not be worlds-better than stock. The cam is just too small.
