Can you take your car somewhere remote where you can really run it hard to simulate repeated track-like acceleration and get it very hot, so you can test the work they did? If not I recommend taking it to a dyno with a tech who really knows track prep, they can run it out to redline there and simulate track accelerations, Katech knows how to do this I assume others do too.
I have Willow Springs skidpad (which is really like a small oval track) only 75 min away and I sometimes take my car there to shake it down and practice car control prior to a track weekend. It's test and tune open track rules at the skidpad so very informal.

Yes, exactly. Dealer swapped coils to see if the misfire jumps to cylinder 4. Their reasoning for doing this is since they cannot reproduce the misfire.
Unfortunately, I don't have an open area to do some testing. My next DE event is in a couple of weeks, so getting to a dyno before then will likely be tough.
At this point, I'm planning to do a few things:
1. Run some Techron through the fuel system in case my issue is related to a dirty / stuck injector
2. Purchase a spare ignition coil to have on hand at the track
3. Bring spark plugs & gap tool to the track
4. Get a more advanced OBDII scanner?
On that last point, I don't need HP Tuners, but is there laptop software or a handheld scanner that will give me more information than what I currently have? My scanner is an
