Who's tunes?

First thing I'd do is remove the CAI and clean the TB, then reassemble and make sure there's no air leaks. A custom tune can amplify little issues like a dirty TB which is known for causing idle problems. Sometimes you can overtighten the clamps and slightly warp the tube at the TB. Also, if you also reset the adaptive learning by having the battery disconnected for a while, then you need to put a few miles on it before the settings settle down in some cases.

The tune is from stage3 tuning from stage3 motorsports

how long would you have to leave the battery disconnected for

The CAI is either leaking air or the tune is garbage. I vote tune.

I'd still clean the TB anyway. Many people have had idle issues with less than 30k miles due to a dirty TB.

Disconnecting the battery for about 20-30 minutes clears the adaptive learning.

I will clean the tb do you think that is why it is stall while im driving it too?

Nuke

It's a possibility and a likely one at that. It may also be the tune. Try the cleaning first, then contact your tuner if it persists.

Why would you buy a tune from stage 3 motorsports? What makes their tuning better or even good?

It has to be the tune or the install of the CAI at fault.
