I personally like the Turbo Blowoff valve sound

Is there a way you can make a supercharged 3800 have the same sound when you let off the gas while in boost?

The car returns the air back into the intake correct? so that means the pcm is expecting that and calcuclates the air/fuel for the extra air? so would making the extra pressure blowoff into the atmostphere mess with the air/fuel?

Just an idea
