My LTFT's have gone up around 6% since installing an LS6 intake. This is a normal amount for it to go up isnt it??

I don't think the trims should move at all, it's just slightly
fatter pipe. The only place the intake should have effect
is up where you're well out of closed loop anyway. If you
see the low end cells being messed around then I doubt
the intake manifold is responsible per se.

Intake gasket sealing however should be double-checked.

My way of thinking was that since I added more air flow and HP, then the air flow numbers would have to go up as well. And since i didnt do any tuning since I put it on, the PCM would adjust for the added flow by adding a bit more fuel. Am I not thinking right here?

you are right, VE is just another form of describing airflow. you can convert them too, if you have EFILive you can view every VE table as either the special GMVE units, dynamic airflow, or cylinder air
