yeah i'd almost guarantee the egr would cause it not to smoke, and the pump might be de-tuned in order to meet whatever california emissions there were at that time, smoke is not desirable though, granted with power on a 12v smoke is pretty much natural
you need to get rid of the dang egr system thing that is on there and then start modifying the pump and stuff if you want to go fast
you and that egr hatred

Truthfully, he'll want gauges if he does anything more than an intake/exhaust. Messing with the afc and plate are gonna mess with not only boost, but egt's.

Like I said, the cooling system on these trucks are great. Diesels naturally take forever to warm up because of this.

A stock diesel made after the 80's shouldnt smoke at ALL. If it did, I would suspect something is wrong.
No there is no smoke button. You sound like my 18year old cousin; he wants to buy a diesel so it can smoke. Just grab a damn chisel and a damn screw driver and go to town on that pump.
