01 f250 7.3 smoke.

[Usmcmudslinger]

So I know I'm gonna get hit on it but I hope at least one person can help...(no its not to smoke ppl at the red light) but I have a 01 f250 7.3 with a 4stage bully dog..I've seen some trucks smoke like a train!!! How can I get my truck to smoke more? Can anyone help? I have to put it in "race mode" and pedal to the metal for it to spit a little bit of smoke...and I'd like it to smoke more, any ideas?




Thank you.

With the BD, it's probably maxed out on tuning. A custom tuner may be the only way to dump more oil and fuel and limit boost. But then you'll just run out of oil and
fuel.

Those trucks probably smoked because they had HUGE injectors with tons of fuel and giant turbos that take forever to spool up. Notice, once they spool up, there's no smoke

Yours isn't smoking because it's making a proper air to fuel burn. Also, you'd probably stop it once you notice what your EGTs do when you do that

There's a proper answer. Get ready.

Sounds fair and good enough... appreciate the help. Another question is it normal for the truck to seem "powerless" when is cold?

Yes, this is for your own good. It limits power until you are up to operating temperature so you do not ruin anything.

Well it's a diesel. Diesel does not have a spark to detonate fuel. It compresses a lot of air into a small space, injects liquid diesel, which then ignites. When just using compression to combust fuel, heat helps drive the burning process, as with any fire basically. Since the entire motor is still cold and the only thing making heat is the glow plugs and compressed air, the burn isn't as complete or powerful.
Also, the PCM will retard the start-of-injection process to help protect the motor. This way it gradually warms the block up.
The last thing that might be the reason for the lack of power is the ExhaustBackPressureValve. The EBPV is a butterfly valve after the turbo. It's sole reason is to close during cold weather running until the motor warms. It increases back pressure, making the motor work harder and holding in that exhaust longer to heat up the block a little faster, but still safely. Most unplug the actuator for this as it doesn't really help the majority of us.

Oh hell sounds pretty technical bubba, really appreciate taking the time....this things are pretty sweet...
