ok so i got a stage 2 installed today and left the dealer and went home and put a step colder plugs in now i notice that my check engine light is on is this normal and will just go away by itself or should i get it checked out? please help

 

Take it back, and check your gas cap.

 

without the code no one can tell you what it is. no one can speculate. it could be 2 billion different things. since you had it done at the dealer, take it back and tell them to fix it.

and now i notice when its idleing that there is a loud noise like air sucking threw something that i havent heard before?

 

^^^Bring it to the dealer as soon as you can.

 

Are your plugs tight enough !!!!
If you can hear the noise listen and track it down .

 

it sounds like the noise is coming from the injectors or right around them anyone know what it could be its def air sucking in somewhere?

 

If they screwed up the grommet that sits in the head it will cause it to leak. It's also possible that they installed the injectors without lubing the o-ring's causing them to roll and not seal correctly.

If you hear a noise it could be quite a few things including ..... supercharger to intake tube couplings ... supercharger manifold gasket... various vacuum lines. Do you smell fuel at all? Good luck
