when to get bigger fuel injectors?

[pontiacmanj2]

Im going to be moding my 04 comp g soon. im not doing any internal parts, just mainley add on parts like inake, headers, exhaust, tuner stuff like that. Im pretty sure I would have to get bigger fuel injectors, Are would the stock ones be ok? Info needed please and thank you Johnny

If you don't plan on doing a cam then stock injectors will be fine

Or intercooler or E85.

Forget what I was looking at but on the 04+ the scan tools will show quite a bit longer pulse width than your injectors are actually seeing.

Guy used a scope to confirm this.

Anything below a 3.5 pulley after headers and a tune.
