Sketch sound after flash to stock
 

cant think of a word that would describe this sound but it resembles a whining noise you would get when cranking an old school beyblade where teeth would be cranking on a gear. Anyways I reflashed my car back to stock, and, during testing, that sound came up when idling. Also, after it cooled down, the car sounded completely fine afterwards. No leaks whatsoever so I figured it was the tune. My original tune had a complete exhaust setup, intercooler, and it's cammed, and now everything went back to stock other than the new Omni 4 bar, grimmspeed ebsc, and the cams. Afr's weren't crazy either sitting at 13.8 +/- 1.0
on the other hand, this could also be the water pump since it hasn't been replaced from factory and the mileage didn't reach 60k yet--which would be a factor since it just started to get warm at around 70 degrees in sf

Here is the tuneAttachment 260703

A better way to describe the sound would be a ratchet moving backward or your parking brake engaging and hitting the notches. Those sounds but toward the passenger side by the engine. Timing off?
