Smoke Question
I hope this question is not to stupid! I am just trying to figure what is causing the excessive black smoke. I know it is common for black smoke when you use a programmer but it did not use to do this so bad. I have a 2000 F350 4x4 CC 7.3 with 157,000, I change my filters frequently and I usually run the 85 hp on my Prediator. If I drive slow (the speed limit) around town in OD it seems to be lugging and blowing out black smoke or if I start to go up a grade and make some boost I really dump black smoke, just trying to figure out why because it did not used to do this even with the Pred. I have tried the lower HP settings and it still does it maybe a little less. I know this is a little long winded but Iam wanted to explain. Thanks

Whats going on with your exhaust. Do you still have a muffler. How about a cat. Could they be clogged somehow? I have been running a Dp tuner chip for some time with alote of black smoke. I just learned all the smoke was do to my restrictive exhaust. No cat but did have a stock muffler. Took that muffler off and went to a 4'' dp to 5'' exhaust no muffler. Now with the chip in the 80 setting I have to try and kill it to get good smoke. Also any noticable difference in egt's?

I replaced my muffler 2 years ago with a 4" flow thru muffler and I do not have a cat. I have a ford AIS Filter with the fender boot and the filter minder does not show that it is restricted. I will have to try and check the boost sensor my gauge shows boost and if I really punch it my SES light goes on at about 26 psi.
