Some aftermarket CAI kits require a custom tune in order to run properly. If yours doesn’t, then I suspect you have unmetered air entering the system. When this happens, your MAF can’t send accurate information to the PCM and your calibration is ineffective. Please investigate these possibilities, and if all else fails, you should return the car to stock, and get a refund IMHO.
