Tuning question.. Fuel / Timing ??

[ebusa]

Hey Guys,

I've noticed with the more higher HP tunes when reving up in park a good amount of black smoke shoots out, or even driving and when the excelerating rapidly before the turbo spools up. I realize this is just overfueling due to the turbo not on a load cleaning it up.

However, I have a TowAgg tune from Vivian @ QT's and this tune also shoots out black smoke while other tow tunes from other vendors and even some street tunes don't do this.

I'm guessing some tuners use (more timing, less fuel) and more (fuel, less timing) than others?? Is one safer than the other? The tunes with more smoke seem to run smoother, more powerful of course

Thanks

more fuel less timing is usually for trucks with stock bolts, its safer.

Any Diesel is going is going to smoke if you just punch it and wait for the turbo to spool.

Thanks for the reply! I just noticed that vivians tuning seem to smoke more than others and am suprised to see this much coal on a towagg tune.

The TowAgg runs excellent and very smooth and linear power. It even sounds better. It accelerates effortlessly and actually feels like my truck is lighter and not trying so hard to get moving.

I never had issues with smoke on tow unless it was hammered before it lights. Now my current tow/street tune can roll it but its not really made to tow even a mild heavy.
