Just wondering when you really get on the gas, if it is normal to hear what sounds like air being released out of the engine/supercharger. Kinda like on a turbo charger when it dumps. Just wondering if this is a normal thing to hear a kinda swoosh, when engine switches gears. Thanks

 

Mine doesn't sound like that.
Are you stock or modified? It could be the sound of the air intake sucking.
Best thing to do is to record a sound clip and post it up so we can listen.

 

its probably the supercharger kicking in ,mine has whistle b/c of the k&n air filter

 

thanks guys, ill get to work on trying to get a sound clip. also sounds like the EGR tube could be going, because im also getting a puffing sound, when i really get on it. as far as i know everything is stock.
