If it has a pop, or sneeze, it is more than likely lean.

Sounds like intake reversion.... it's normal and the 57 is known for it. Open air cleaners make it worse... I put a Ventilator AC on mine to quiet it down.

I believe its your map, as I installed 57h few months ago and never witnessed anything you described.

Many complain about the 57 reversion noise; very common and, as Rockout says, open air cleaners just amplify the noise.
