First run last week
I went back to the same shop to get a second run today. Weather was very different this time, dryer and hotter. I took my giant orange home depot fan to run under the engine bay. We let the truck sit for about 45 minutes on the lift with the fan running.
Run this time
This is the info they gave me from todays run
