injectors/ and tuning computer

[loboreno]

When do you really need bigger injectors? I have a 3.0 . Full 60k tune up, x2j computer, eh intake, bbb taylor 8.2 wires , high flow y pipe, 2 1/2 exhaust into 2 super 40s. Everything else motor wise is stock. I had stock injectors clean few years back. Anyone have some advise. Please??? Also with the x2j computer when should I worry about changing the tuning?

Generally you wont need injectors unless you are running boost. If you find you are running lean then you would need to run a Tweecer: SHO Source

You can then run 36lb injectors: SHO Source

You would need to upgrade the fuel pump: SHO Source

You will not need injectors for your setup. Tuning, on the other hand, can improve power, drivability, and fuel economy.

with bbb

Should I keep the intake horns in or take out? Should I leave tb stock or go bigger when I get tuning done

You need to remove the horns with big bore butterflys.
They will be a restriction.

A bigger throttle body Isn't necessary at this level.

The stock injectors are fine. No need to upgrade.

I recommend a new fuel pump, especially if it's never been changed.

A tune will help in all aspects.

Enjoy.
