I just bought an 07 Spyder, and the car whistles under light acceleration. I tried several other 07 Gs at Lamborghini - Miami and they all did it. Apparantly, Lambo is using a new type of filter (somewhere in the engine) and it whistles. The tech guys at Prestige reccomended trying the filter used on the 06 model. Has anyone done this - or experienced this problem (must have windows open to hear the whistle).
