I got myself an 09 ss so far it has k&n intake catback exhaust and a super chip tune. That great for a start. In the past year I ordered zzp dp and wesco pistons which I haven't installed yet. I need to look at larger fuel pump and injectors any idea what the factory limit on the fuel pump and injectors is?

 

For the parts you have listed, I'm not seeing the need to go with larger injectors. Do you have some future mods planned such as a bigger turbo and maybe some head/cams work?

 

There's no bigger injectors or bigger pump. You can run zzp cams with larger cam lobe for hpfp. Then a 5th injector if you still need more fuel. Like stated above there's no need for fuel mods unless going big turbo or e85.

 

yes I have more mods in the future. the zzp cams larger IC piping and IC. my goal is to safely support 450 hp and roughly 380 fpt. so if any one has any good ideas for me to meet my goal please let me knoiw
