Need some help installed vmax ported throttlebody, rx catchcan and breather and the check engine light came on onstar said air fuel ratio is not where it is exspected can I do a fuse pull to let it relearn what is now normal? Has this happened to anybody?

With the breather you need to unplug the air hose that goes to the intake. That should fix the issue, but I could be way off base here.

The hose that goes to the intake and where it goes to the engine have both been capped is this right?

Based on the AF issue reported, the TB is most likely fine and it has to be the breather as it allows unmetered air into the engine. This makes it initially lean and PCM has to overcompensate and add fuel. If there is enoughy compensation a code sets.

So I just got back from the shop if I understand correct thats exactly what happened comp was maxed out at 24.18 ( i think 25 is the max) he cleared it i will have to see once I get it on the freeway in the morning. No code was thrown on my 10 min ride home averages speed 40 mph

If you scan you may be surprised at your LTFTs, even with no code thrown.
