Tuned up but no black smoke

[danr]

Hey guys got my 4" magnaflow exhaust on my 04 yesterday and hooked up my new sct programmer which with the canned tunes impressed the hell out of me, but I was really surprised to see no black smoke. I figured I'd at least get some light puffs but nothing is this normal? This is my first diesel I've owned and done up myself so I'm still learning. Eventually plan to get custom tunes but went over on the budget as it is with everything. Let me know if this is normal I know that less black smoke the better the fuel burn but wondering if it could be a lack of fuel supply

The less smoke the better. The only way you will know what your fuel system is doing is to install a fuel pressure gauge.

Canned tunes suck. Try custom tunes. Then again good customs and you won't smoke either.

As said, no black smoke is what you want to see. The canned tunes suck, get some custom tunes and don't look back.

Lol that's kinda what I thought and the custom tunes will be coming soone is there anyway I can get my insight to read my fuel pressures and if so what's the proper pressure to be running at

You will have to buy a probe. You want it to be running in the 45-75 PSI range, no lower than 45 PSI at WOT, and no higher than 75 PSI. The blue spring upgrade will put your pressure around 65 PSI.

I've geared about the blue spring upgrade is it a wise thing to do or doesn't really do much?

It's wise thing to do to make sure your fuel injectors stay healthy and have enough pressure at wide open throttle.

It is a new spring that replaces the factory spring in the fuel bowl. It will up the pressure from 55 PSI to 65 PSI. It is a wise upgrade.

Not necessarily... The health of his fuel pump will determine the pressure at WOT. He needs a fuel pressure gauge to truly determine the health of his pump.

Thanks I will look into the blue spring next question I'm looking for two custom tunes that I will get down the road I want a good towing tune for heavy hauling and one good hp tune for good fuel mileage and that I can get some power out of I'm a contractor so I'm on the road a lot and tow heavy loads so I need it to be reliable who do you suggest and we're can I find them
