Yep still have that! Only at WOT, and is either a long or short whoosh/whistle depending on how I let off the gas. I think it may have something to do with the edelbrock insulated heat gasket that I installed. I thought about removing it and driving the car with out the gasket or installing the 1" spacer again to see if it goes away.. That is the only thing that changed. Im going to play with that this weekend to see if I can figure out what it is.. I can keep you all posted on that.
