where did my smoke go

[00powerstrokin]

when i first got my bully dog 6 chip my truck would smoke so bad that you couldnt see the cars behind me. now there is hardly any smoke and it just doesn't feel as quick as it was. any ideas? fuel filter? it has no top end acceleration

I recently changed my fuel filter and gained alot more smoke and power. My was pretty clogged up,

I should probably change mine as well. When I first got my TS chip it seemed to smoke like crazy, now, while it's still quite prominent it does seem to be a little less upon acceleration....how often are we supposed to change those things anyway?

You wrote in the right forums! I, for one have had problems with with the back pressure valve. To describe (as I am not good with remembering the technical names) I was having some issues with my (ABS) light staying on and also with my exhaust brake no disengaging when I was at a complete stop. So we ran the diagnostics and it is a sensor that is located in the rear end of the truck that essentally tells the rest of the computers what speed I am going. This effected the exhaust brake in that it is supposed to totally disengage at or under 35MPH. I really don't know exactly how it effects the (ABS) system, but do know that it is directly related. I also forgot what the code was that it gave to me initially and if it comes up again I will let you know so that I can share with you all what the actual sensor is.

If this is too confusing, let me know, otherwise, I hope that this at least gives you a starting point!

did you recently change your air filter? or brands? mine stoped smokin a lot when i switched to a k&n. lost even more when i did a filter mod. but it flows more air w/ cooler temps.
