Low idle start up

So for the past few days, every time i start up my car it on goes up to 1200 rpm and drops to 800 rpm fairly quick. I live in texas and its currently 90 degrees outside. its doing the same start up, as cold starts when the snowflake appears in cold weather. My normal start ups used to go up to about 1600 rpm and immediately drop to 1200 rpm for a few seconds and then down to 700 rpm. I've tried to find answers here but no one has had the same issue. Any advice on returning the car to its original idle
Ps. I did have my car serviced at a VW dealer a couple times for carbon cleaning and stuck injectors. Looked for for vacuum leaks post maf sensor and found that they left the coupler clamp for my CAI that goes to the turbo completely loose( pulled the whole piping off the turbo with one hand) and was also missing the bolt that holds the CAI piping to the engine. Re-tightened it, got better throttle response but it did not fix my idle issue.

I see your APR stage 1, what version of the tune do you have? Previous versions of the tune had cold start issues.

During the summer the engine doesn't have to try as hard to heat up the cat converter, so rpms aren't as high after a start up. It does sound a lot like the old apr rev issue though. The revs you're getting now sounds normal.
