ISX smoking & sneezing

[lonewolf]

Ok. Now that being said and the ranting and ego stroking is done can we get back to the problem at hand. I'm not the a$$hle honking and calling you names. Personally I don't care what kind of truck you or anyone else drives.or what speed they go. As long as it doesn't create a dangerous situation for myself and those around me. I also think blasting down the highway is rediculius. But creating a road hazard is also rediculius. I was just looking for an answer to the question of what could be causing the sneezing in the truck. I've already done your egr tune up didn't find anything and didn't change anything. I've already changed ALL of the sensors pretty pricey I might add. Didn't change anything. Had new head put on because of fuel in antifreeze found when changing sensors. Motor and computer all set to factory spec as im trying to find what could have been done by previous owner to cause all the problems. Then get it to hopefully someone on here to properly tune it so that it CAN be more efficient. Im not looking for 20mpg or monster hp and torque. Im looking for a reasonable efficency and reasonable performance. And considering that I am mostly empty, bobtail, or may have 60000lb gross. I dont care what kind of truck you drive . If driven properly it should be able to get better than 5mpg bobtail at 68mph when setup properly and tuned properly. I've reached out to a tuner on here that I believe is in my area. To be able to discuss what this truck is expected to do and proper setup but haven't heard back from him yet. Thats why I was wondering what to look for next.
