John is dead-on... Diesel tuners make a HUGE difference. They add 10x the power and torque of a tuner on a gas motor. If you use a DiabloSport or Banks tuner (or any of the other big name brands) you'll see enormous gains out of a diesel, whereas a tune on a 3800 might yield 5-10hp. With just exhaust and a Banks Six-Gun tuner a friend of mine ran a 13.9 with his 2005 F250 Superduty. Absolutely amazing stuff.
The downside is that once you've done the easy bolt-on stuff to a diesel, changing bigger parts (heads, cams, turbo) is pretty pricey. A cam swap in a 3800 might take $500-$1000, whereas most diesel performance sites don't even sell
cams for diesels. It would probably be many thousands of dollars to do any head or cam work on a modern diesel. Even head stud kits cost $500-$800.
Diesels have huge amount of flexibility right from the factory. It'* expensive to get extreme with them, but they can handle a TON of power through tuning and simple bolt-ons.
Great job, Nate! Those are AWESOME numbers! I bet that truck hauls some serious @ss!
