Over boost

I am going to install a new Wicked wheel 2 and 1.0 housing on my turbo. Will the 7.3 defuel with a overboost? or just pull a code

Both.
Tuning can defeat it.

It will defuel at 23 psi if I remember correctly. You can prevent this with a boost fooler, or most programs will prevent it as well, but you will still get a light unless you put in a boost fooler.
