I just installed 1600cc secondaries along with a FPR in my fd. I have a Power FC in my car but it is untuned. When i turn the car on, it just hunts through the rpms a lot and breaks up when i slowly rev the engine. I was wondering what was causing this and how can i fix it. Also I need a place to mount my FPR so if anyone has any ideas please let me know. Thanks

Did you adjust the FPR?

 

I mounted mine on the front of the upper intake manifold.

You should check your fuel pressure.

And adding 1600cc injectors without a tune is just going to make your car run stupid rich.

 

Check for vacuum leaks.

 

Did you change the injector size in the pfc? You can only go to 1300 i believe unless you have a datalogit not that this would effect your idle. I would definetly play around with your fuel pressure

 

Thanks for the help guys. I will do what you suggested and hopefully it will work. Thanks again
