Got one in here now with CEL. Lifted, 22 inch tires, MBRP dpf back, aftermarket intake. Codes for dpfe correlation (back pressure numbers dont add up), MAF, IAT. Has a brake line leak where its rubbing the frame (installing the lift, he had to relocate the line). He's screaming about "new truck, allready needing repairs!". Here we go again! Will they never learn?

 

yeah thats been a common porblem. If its a AFE intake they usually throw codes you got if used with a DPF back aftermarket exhaust. I had that problem tell i got my DPF delete tune.
