I got a 2004 Nissan Frontier S/C. I just got a cold air intake for it and when the engine is opened up, the supercharger (Eaton M62) actually sounds pretty cool in person. My truck inhales like a fuckin' rhino when it is just sitting there idling lol. Pair it with the cat-back with size-up piping...

Yes this is normal. And do not overtighten your chain.
