Trying to troubleshoot voltage and idle issues in 2011 Auto corvette and wanted to see a stock log before moving on to the next thing. Seems to run okay after Mechman alternator and redoing wires but in stop and go traffic the voltage starts dropping and i can tell theres a rougher idle. From corvette forum posts i saw most people are seeing consistent 14.5 so im not sure why i am not.
Attached my long drive home from work for reference. Been trying to learn the tuning/troubleshooting on my own but think its time to get some help from the community.
