Oh the wonderful hiss! One thing that could eliminate that sound is a piggy back system of some form for the ECU. the sound is around2.5-3.5k....program your throtle position sensor just slightly in that RPM range and it will disappear. As far as getting the right piece of equipment to do that, I have no clue...I'm kind of a rip the entire ECU out and replace with standalone kind of person, so I have zero knowledge with the latest piggy back systems...food for thought.
