The vacuum line to the Secondaries has been removed. The secondary port throttles may have been removed or tied open.

What is the reason that would be done? Will it affect performance? Does that disable valet mode?

If what I see in the pictures is correct, it would mean that the engine runs with secondaries open all the time, using all 16 injectors. ECM program change was required and the Valet Mode is gone.
