Im looking to get some new injectors for my 87 GTA and i was wondering if there is any notice in performance increase. Im getting them because i plan on supercharging and it only requires 24lb but should i go with 30 for better flow will there be any difference. Also some reccomendations on some injectors thanks alot

 

You won't notice a performance increase with bigger injectors unless your motor needs it.
A set of 24lb Accel or Ford motorsport injectors should be OK but with a supercharger you could get away with running 30lbers.
Just make sure you burn a new chip for them!

 

I have an aftermarket chip but i dont know if it can handle 30lbs is there any way to know

 

Unless you told the person that burned your chip that you are using 30lb injectors then it isn't set up for them.

 

so maybe i should just get 24lb ones that way i dont have to spend the extra cash for no performance increase, because if i get 24lb i dont have to change the chip correact?

 

You won't have to change it but your car would run better if you did. You should get a new one when you add your SC so maybe you can do it at the same time.
