He's got about 291k miles on it. Already did an intake system for it, we recently started this:

Unboxing the SuperFlow 4" Exhaust from Heath Diesel (http://www.youtube.com/watch?v=0JzuZMbJMZw)

and

A comparison between stock and the Super Flow 4" (http://www.youtube.com/watch?v=gFm-u2BElQ0)

I'm still working on the before/after video of the exhaust upgrade, but I'll update this post when I get it done and uploaded.

Initial impression - HOLY CRAP what an upgrade. Sounds amazing, deep and mellow. The difference in throttle response and power makes it 100% worthwhile.

So far we've also done the dual thermostat upgrade, with the 130pgh waterpump, and a Mishimoto all-aluminum radiator.

Today we're going to be installing gauges (EGT/Boost/Trans Temp), A-pillar pod for the gauges, and installing the B&M 70274 for the transmission.

No problem! Love working on stuff, heh

Video showing a bit of the audio difference. I've got some in-cab videos I'm working on right now.
