White Smoke Only When Letting Off The Go Pedal
Truck recently tuned. HS mini max on the mild setting. DPF/DOC delete. Has been on for 400 miles with no prob.
Today I drove it @40 miles steady and noticed when I came into town white smoke. Accelerated away under moderate power and no smoke. Moved my tune to stock and same thing.
Called Zack at Performance Diesel? I think is the name. He had me uninstall the tunes and reinstall. No change. Do I have a cracked EGR cooler? How do I verify? Can I just block it off?
Any other suggestions.
