I don't normally drive my truck hard, but when I came home today I was curious to see what psi the turbo makes if I stall the truck up like I was going to drag race. I had the truck in 1st gear and the DP on 120. I only did it for a few secs but when I let off the OD light was flashing. I killed the truck and let it sit a few minutes, then started it and drove it around. Light went out and truck shifts fine. Any ideas on what I did to throw the code?
