No Smoke??

Hey guys, I have a 2005 f250 psd with a 4" mbrp tb exhaust and sct x3 tuner with innovative tunes. I havent been in the diesel world long but it seems like everybody with a tuned diesel on here roals coal when they lay on the skinny pedal and my truck doesnt really smoke at all. Not that its a goal of mine or nor do i really care to but it seems to me like it should. Is this normal? Just courious thanks guys.

Best way to get smoke from your set-up is to give it some pedal, let off until the RPMs drop completely down. As soon as they bottom out, romp it..

If it still doesn't, you may be looking at a "weekish" HPOP. It won't give you enough oil pressure to let the injectors give enough diesel to really get the fuel moving..
The truck will still run, yours just may be a hair weak..
Because mine will never pass a smog test.. lol

But yours being an auto, it will only smoke for a second or two until it shifts..

my truck runs like a raped ape, it never kicks out any smoke unless its dropping a gear towing, or from initial idle dropping the hammer, then its just a lil puff, wouldn't notice it unless you were watching for it like a kid at christmas (me looking in the mirror! lol)... i kinda wished it smoked a little more sometimes, but my truck runs great so i dont complain... i have read that smoke don't equal any performance gains, so haven't worried to much, but will be interested to see any other insight posted...

Ya. That's what I was saying. If it's an auto, it's not going to smoke much.
Mines a stick, so I can put in 4th and lug it down to roll the coal 'til it blows up.
And smoke is wasted power btw.. It's wasted diesel, really wasted power.

It's fuel molecules that didn't get paired up with Oxygen molecules.. So it gets vaporized into black smoke. Usually, air is the limiting agent in the reaction. That's why bigger turbos and/or NOS
is added to equalize the ratio..
A lil chem lesson for you. lol

As already mentioned, you may have mechanical issues.

If its tuned correctly, you'll hardly get any smoke. How does the truck run other than the lack of smoke? Does it feel like its pulling strong? Does it nose over on WOT acceleration? Have you put it on a dyno or taken it to the track?
