You might consider installing ISTA on a computer and hooking it up--I have had instances where it gave more info than phone apps.

I have had this problem with my car for years. Only does it when its warm and parked for a little bit. If I rev it up a bit totally gone! If you find the issue please post it!

I decided to lift my car and check the charge pipe again and I found the 2 bung holes with no screws on the bottom of the pipe. I think the screws fell out when driving which was causing a boost leak and probably giving faulty readings to the MAF causing the revving. I closed both of the holes with screws from Home Depot with basic 1/8 NPT thread and loctite So far it’s been 2 weeks since the revving has stopped so hopefully that was the only issue.

Turns out it was just a boost leak caused by the VRSF charge pipe from the bung hole. The screw plug had fallen out on one hole, other one was quite loose. Got a new plug for the first hole and added some loctite and took the original screw out of second hole and added loctite and tightened that as well.
