Smokless?

[843Powerstroke]

yesterday my buddie installed the superchip programmer on his truck which is the same year and all as mine and he has an intake and unbolted exhaust from the stock down pipe. His dumps alot of smoke. Then i unprogrammed his and tried it on mine. No smoke what so ever. The only thing that i can think of is that i have the egr delete kit and he doesnt. Im also he still has a cat. up in his exhaust from where he unblolted it. Why would mine not smoke?

could you feel a big power diff? If not,the superchip locks in his vin number even when you set the truck back to stock and will not work on your truck untill you get superchip to re-flash it are something like that (i think, i know some works that way)call superchip they will help you.

The egr should be closed at full throttle, but it will normally increase visible smoke if it opened slightly or was stuck open. Also, depending on mileage, his may smoke more from wear. Superchips tuning is rather conservative to begin with aswell...

When you uninstall the programmer back to stock it unlocks the vin-lock, the programmer was working at 100% no dought, huge power difference on my truck.

The better the tune, the less smoke. Smoke actually does NOT equal horsepower. All that black smoke is actually unburnt atomized fuel.

You having little to no smoke means you're burning all of your fuel and are running lean (or perfect) or that you have some sort of cleaner in your exhaust, and while it was a bit hazy, I think you said that you are straight piped?

So my guess is that it's running top notch for ya. Or you're lean on the fuel and can be getting ready to blow something.

Yeah it is stright piped, 4in turbo back. I hope nothibng is getting ready to blow, how could i find out if i am running lean? install an air fuel ratio guage? Oh and there is no cleaner in the system, thanks for the feedback

What year is your truck? if its an 03 the turbo in the 03 trucks is known to flow more air = better combustion thus less smoke.

well the egr delete helps alot with smoke but you stated that he dumps alot of smoke. I am not sure the egr delete will contribue to THAT much of a smoke difference.
