if i were to run the BBK intake manifold visually it would not pass SMOG here in CA. well if i were to use it and then put my stock ls1 intake manifold back on come smog time and switch back to the BBK after SMOG would that mess up the tune at all? cuz if it does i really would not like to have to get a re-tune and am gonna try to figure something else out.

 

God smog states suck. I would think it would possibly just make it run a little rich since there would be less airflow. It probably won't be too bad.
