I bought a 2006 4.8 a while back but have decided to go the LQ9 route so that is in route to me. A 2004 LQ9

I am either going to do the LS6 intake swap or the L92/LS3 swap.

If I just do the LS6 swap, can I use the ECM, TAC and Pedal from the 4.8? The LQ9 didn't come with those items.

I was planning on using the new Painless system that has their own ECM with it. Going to use the DBW on the LQ9 but the 4.8 is DBW as well.

Thoughts?
