The computer threw a MAF insufficient code, which it does when it looks at various sensors on the car and predicts a range what the MAF should read and cries foul if it doesn't fall in that range.
Being a cool and rainy day, my IAT sensor located in my lt1 airbox was reading exceptionally low, which I strongly suspect was the culprit. Car ran fine and the other sensors seemed to read OK. Cleared the code and ran for the rest of the day with no issues.
If it's an ongoing issue I can just move the IAT upstream where it will be exposed to more heat. I will pick up a spare MAF to be safe.
After that during the last session I could hear the torque arm tapping, looks like I lost the front clamshell bracket stud/nut again, that hasn't happened since 2014. At least this time the outer bracket was just hanging there.
Got home and napped for a few hours, probably 4hrs of work, pull shocks and wait for them to arrive during the week and I'm all set.
Prior to this track day all I did is install an oil thermostat, replace the fan, and put in a new pinion nut.
Glad to finally be getting to the point where work between events is somewhat minimal, and being able to drive the car between events again.
