On idle and when i hit the gass it sounds different but you can deff hear it. should i be worried?

 

when i hit the throttle a little bit i can hear the noise, and it gets louder when i get higher up, any ideas?

 

post some vids!

 

Consider the fact that every cylinder is holding a fuel, air and when it burns it's similar to a small explosion. Now bore/stroke out your motor making the combustion chamber larger. The tune that's updated will add certainly have more timing than a stock motor to allow more air to fill the chamber. With more air you need more fuel. So now back to that idea of a small explosion (really burn) inside that chamber. What's louder, one pound of explosives or ten? More air/fuel, larger and therefore louder burn....... Sounds like as long as the car feels fine when you hit the gas the extra noise should be expected.

 

I like this explanation!

 

It kind of sounds like a baseball card in a bike spoke when i hit the throttle and at idle.
