So throwing those codes plus the regular DTC one. I switched out the sensors, MAP(Boost) and IAT. Did nothing for the way it ran. My IAT was toast as in there wasn't any plastic housing left just the diode i believe.

So checked my grounds, everything looked good. I cleared my codes drove it around the block still same thing, sputtering and not sounding right. So I am thinking ECM?

This is for a 2002 2500 6 spd 4x4. Has a Mopar exhaust brake on it and a Van Aken chip. Plus AFE air filter. Let me know if any of you have any other ideas?

Thanks

 

Take your chip off and see if still does. Sometimes it is good ideal to kill memories in computers. Take BOTH positive cables off with key off. Now touch one positive to the negative. You are shorting the wiring, NOT THE BATTERIES. You will see a very small arc. Hold ground for 32.7 seconds. This kills all adaptive memories in computers and sometimes effects performance. You will also see a very small arc when hooking positive (both Please) cables back up. Remember key off during entire procedure.

 

K i had tried unhooking the box. I drove it around the block a few times with it off but nothing. Didn't think of even trying what you suggested? Haven't heard of that, might have to research that a little more.
