black smoke

[doogie]

my 2008 f250 blows black smoke with dpf installed, i think it might have a crack in it. also has not gone into regen for along time and getting 18 mpg. Only mod is sct? Something is wrong?

just went into regenim just letting her do her thing in the drive way. still smokes black though. has anyone had any problem with their sct not returning back to stock programing?

Well the DPF isn't going to get rid of the all of the black smoke despite what the EPA says, even in stock form......hell I was blown little puffs of black smoke all the time when I was stock......your seeing the smoke because of the SCT programming and more fuel its putting in the motor, but the strange thing is that your truck should be seeing regen more often than stock......I don't think there is crack in the DPF, because its very large and there would be a definate change in sound......I do have a question though, do you do a lot of highway driving?

yeah my dads blows black smoke too, and it is totally stock.

i have the sct set to see when it goes in to regen so i know. but it has always been a little smokier than others, when i first got it in 05-22-07 drove it home from the dealer i had black soot in the tail pipe and all the other ones didnt. that i saw on the road.


now the problem is the sct didnt save my stock file. Tried returned the truck to stock still smokes like a tuned 6.0 L and trans shifts hard also, so im sure the stock file didnt re load. need to take it to the stealership for some warrenty work and do not need to be busted!!
