No, you should convert to mass air, then install the CAI. Messing with anything as far as air going into the motor with a speed density car is going to mess it up, they are tuned specifically for values already pre-programmed into the computer, they cannot adjust like MAF cars. I'd PM BillyMich and ask about his MAF conversion kit.
I don't know why the Bama guy posted about getting a CAI, I'm hoping that he just missed the part about you having SD because it would be kind of funny for the "mustang expert" to not know that...
