am i feel wrong or it is normal.
the car doesnt have much response at low range.
also, the guy told me, maybe i need replace the cat and intake as well.
so, right now, i just try to use to it.
changing to injen CAI will cause you to lose low end power---> lose of low end throttle but you should be able to feel the difference but not as much.

and you will need to wear in headers and let the ecu adjust to it.
