Here's a quick run down on my truck. I purchased it around the first of the year and it had already been tuned and had both the EGR and DPF deleted. As far as tuning goes I am not sure what tube is uploaded into the truck. Previous owner was unsure also.

The EGR up pipe was also unbolted and pushed back and the block off plate was mounted directly behind the turbo. Who ever installed this part had the right idea but had zero mechanical knowledge or skills. They drilled the block off plate, put a 45 degree brass fitting into the EBP sensor snd then JB Welded them into the joke on the block off plate.

The truck ran perfect up until a couple of weeks ago which is when I discovered how the EBP sensor was mounted. I pulled it off and cleaned everything up and put together a tube that what tap into the hole that was previously drilled so that the sensor would not be mounted right next the engine. At the same time I installed a new sensor. This seemed to fix the problem for a few days but now the truck has no power until around 30mph.

My Edge Insight shows three little dots until you reach around 30 mph and then it will begin reading 0-3 pounds of boost or so.

I pulled the map sensor out and it was heavily clicked and so was the port on the intake for the sensor. I have also tested the turbo actuator and it seems to be working as it should.

I am hoping to pic up s new map sensor today and try my luck there. I've read what seems like hundreds of similar problems online but have not been able to resolve mine. Any help would be great! I drive the truck around 110 miles a day for work.

 

I pulled a MAP sensor off of a buddies truck last night with no luck of it making a difference. I also put the old EBP sensor back on and it also did not not change anything.

 

Moved to the 6.4L forum.

 

Are you getting any Exhaust Back Pressure Readings with the Edge Insight?


Are you getting any black smoke out the exhaust?

 

Edge doesn't have an option to monitor the EBP sensor. Before I replaced it I was getting EBP related codes all the time.

Quite a bit of black smoke until it builds some boost. Nothing like it was when it was running correctly.

 

You should be able to monitor the Exhaust Back Pressure. I can with mine.
