On the supercharger? No its just a pump so there is no timing. After I put the INlays in my bumpers i thought it drove different. It is most likely your mind messing with you. Im really bad about it becuase i drive alot and even on my new 04 i think i hears 'something' but i don't so you are probably ok... and btw therrrrrrrr grrreeeaaatttt!!!!

now but i think it feels like summer, did we skip spring
