ok i have the turbonetics kit with the 380cc injectors. those are made to handle 300 hp. it also doesnt allow enought fuel so it makes my car run lean. what size injectors should i get. i was thinking 650cc injectors by rc. what do you think?

 

the 380cc injectors can flow upwards of 400rwhp. did you change your fuel pump?

 

Please post more relevant info about your car and your build, and make a new thread in the Forced Induction forum.

It seems you already have a misconception about 380cc injectors, additionally you don't mention anything about your tuning, you don't show a dyno with AFR, etc etc.

You can get some good advice on these forums, but you have to come more than halfway with your info when you post a question.
