Hey guys. I'm new to the forum although I've been using the info for a while now.

Anyways, I recently baught a h&s tuner and installed a dpf delete kit.

Everything works great when the truck is not plugged in to the tuner although when I do plug it in, the truck keeps throwing a communications code and goes into a limp mode until I delete the code. I believe it was p0073 but i maye be mistaken. Regardless it has to do with communicating through the obd2 port. I sent the tuner in to get checked out and it turns out its something to do with the truck. I've checked all the fuses and tried to check for broken wires.

Anyone have any ideas of where to look next?

Thanks

 

Just got the tuner back. It was actually code U0073

 

Are we supposed to just guess what you're working on?

 

That could help eh. 2010 f250 with the 6.4. I've been looking reading about abs problems shorting out but can't find anything specific
