I recently had a Procharger installed and retuned. A couple of days later I had the car in a line at the car wash and after idling for quite some time noticed that the temp gauge was at full hot and the warning message for hot engine was on. Shut it down, cooled of quickly and when driving home normal temps. Started up in garage yesterday and let idle, took 18 minutes but went to full hot on the gauge and warning message again. Thermostat, fan settings in tune?
