[QUOTE="Sagittaria, post: 11926117, member: 113330"] No. The motor is pulling the same amount of air that it did normally (just not through the motor) so no tune is required. HOWEVER, the pcm will need to be reset (battery unplugged for a bit) for it to relearn the idle. This is due to more air needing to be pulled through the IAC. With the stock setup, a fixed amount of air was pulled through the motor via PCV that bypassed the IAC. Now that's gone, the IAC will have to compensate to hold the same idle. This is also why some users report a smoother idle without the PCV, as air is no longer winding it's way through the motor at idle. [/QUOTE]
