Do I Have A Problem
As I made a right turn from a total stop I realized that the car in the lane I was turning into was approaching significantly faster than I had estimated. I was to far into the turn to stop my only choice was to get out of his way quickly. Just as I stuck myfoot thru the floorboard I noticed him start flashing his lights on and off then he disappeared in a large black cloud of diesel smoke.
Here is my concern:
I have never noticed the production of black smoke before but then I haven't really been looking. On the way home this evening I watched and found I could make smoke at will, most easily by just really sticking it at low speed.
My performance mods are quite modest in fact I run the superchip programmer at the "TOW SAFE" (lowest) setting because that is what I mostly do. The 10kmod has been removed because it gave me "Check Engine" lights so the only thing besides the programmer that would affect fuel flow is the FPR shim.
I have read many posts by guys that really have to work to get smoke and I seem to be doing it to easily.
Am I just being paranoid or is this a syptom I should worry about.
By the way I was successful in getting out of the way

I guess I am mostly concerned because I generate it so easily and everyone else struggles to make it.

Hmm. I have a '99 F250 powerstroker with the superchip and it also is set at the tow-safe (because like you, I tow -though not as much anymore, but I like to keep things "safe") and if I tromp on it, it will generate the black smoke. Black is far better than blue, and if you feel the power push you against the seat, (while hearing the turbo wind up -gotta love that whine!) I wouldn't lose too much sleep. If in doubt, however, get a boost indicator and see what the beastie is doing for you.

Sound like its working fine. Make sure your airfilter is clean. You'll get more smoke down low before you really start making much boost.

You are just fine. That smoke is produced as unburnt fuel. Once the turbo catches up it goes away. As you know the turbo is powered by the exhaust leaving the manifolds and turning the turbine which turns the inpeller and produces boost. There fore it takes a second for the turbo to catch up and force more air into the combustion chamber to lean out the air/fuel mixture again. That is why you will produce more black smoke at low RPM's and lower speeds when you romp on it.

Very close monitoring has produced the following observations:
1. Aggressive acceleration without "sticking my foot in it" = no smoke
2.in response to this
Turbo sounds and seems to behave as usual I get up around 20 lbs of boost pretty quick before I back off (usually to avoid running over someone or to avoid getting better acquainted with the local constable)
3. Smoke appears almost simultaneously with the foot stick, before Turbo can spool.
4.In response to this
Periodic preventive maintenance, including new airfilter element, was already scheduled for next weekend.
Conclusion:
I was being a bit of an alarmist; although, I can rationalize my fears by saying I very seldom do the foot stick thing cause I dont race (well almost never) so I just hadn't observed "the cloud" before. wonder what the guy that caused the incident thought when the lights suddenly went out LOL>
Thanks for calming me down dont think I could stand it if I hurt my baby.
