He's out of town with his 30' travel trailer. truck is an '03 6.0/5r110 with gauges, 4" exhaust & dp tuned SCT. He programmed the truck to race mode and took his cousin for a ride (without the trailer) to show off. Said he got on it hard, hit 1300* and let off. After that the truck had no power on take-off.
After asking some questions, it sounds like baaad turbo lag. The SCT isn't reading any trouble codes. But he did say the next time the truck was started cold it blew a huge cloud of white smoke.
I searched various boards a bit... sounds like maybe stuck vanes in the turbo or an egr cooler problem?
