When do you need to add FUEL? Or reach maximum capability of stock fuel system.

I have z1 cai, z1 upper plenum and lower manifold, z1 hfc, ts cbe.

I have 63mm tb but want to put those on close to time I retune. Before I go back to z1 to retune with tb and possibly add headers I want to make sure that I won't be adding more air than oem fuel system can put out fuel to keep a healthy a/f ratio. Am I overthinking this?

 

I'm a bit at a loss of your question. Are you asking when to install a new injection system? If so, chances are you're not going to have to worry about that unless you go F/I.

 

You won't. Yes.

 

Ok cool that's exactly what I'm wondering. I wanted to f/I but desided ill just buy a car that's already boosted. So all motor for now

 

Ok cool just wanted to make sure that I would be able to keep a good a/f without upgrading fuel injectors or pump or whatever. No plans anymore for boost as of now
