Black smoke on acceleration...
I finally picked up my truck (2001 F250) from my cousin today. He has had the truck since around 2010. He hasn't done anything mod wise to the truck. Bone stock. He and I have always speculated that it had been programmed at some point, due to the black smoke on acceleration. It's not anywhere near "rolling coal". The previous owner had pulled a 5er with it, which is my intent as well. Correct me if I'm wrong, but the truck shouldn't smoke AT ALL without being programmed, right?
My cousin bought the truck with about 96k on it. It has 212k on it now. It has run exactly as it does now since the day he bought it.

Check the factory air intake housing. I noticed mine wasn't fully sealed and clamped down. Allowed more air to come in which caused a decent amount of black smoke on acceleration and letting off throttle. After fixing that it went away. Though now it is back, but less with my new S&B CAI install.

If trucks' been unmolested since 2010 and had a decent working life before your brothers' purchase, id have to say that theres a boost leak or 2 going on. Your intentions with it now will be less troublesome by inspecting atleast the plenum boots. A set of riffraff cac boot kit and clamps is work looking into, along with the plenum inserts. Inspect the uppipes as well for blackness...combo of leaks with unburnt fuel equals black smoke

I agree with Timmyboy, black smoke is improper fuel/air mixture. I only see a wiff of black smoke on the 80 HP tune (DP F5) at WOT. Not sure if my sig shows the IH bellowed up pipes and RR 6x6 wheel or not. ~ 20 - 22 PSI boost.

Mine will blow black smoke first time I push it hard in the morning when engine is still cold. After that, its pretty much not noticable.... at least from the driver's seat.
After I changed injector o-rings years ago, it was pretty much smokeless for a long time. I do have a boot leak, but I been to lazy to get in there while its so hot here.

There is definitely NOT a lot of smoke, and it only happens at WOT. It has done it since he got. The truck in 2010. The smoke reminds me of my 2000 F350 that had the ecm flashed. This tris runs a little better than I would expect it to run if it wasn't tuned. I suspect it was programmed with something like a superchips programmer. If I had to guess, I would say it would be equivalent to a 40hp tune or so. It definitely runs better than my F350 did stock.

Have you checked for codes to see if it has the P0603 code? If it does some tuners will trip it, if so it might have one of the old school Hypertech programers or other programmer from the early 00's.
