Threshold for Pain: How much can your diesel take?

It's a really quick old truck at 6,200 lbs, locked in 4x4 with a 18 lb boosted launch. 0-50 on the street it is hard to outrun, as alot of mustang and camaro guys have found out, when they hear the turbo starting to spool they loose there mind and stomp the gas and roast the tires as I drive away, it would be close if they could get off the line.

It's not funny to them when a dually 4x4 grandpa truck outruns them, but it is to me.
