I have a po103 code some times I have efi live now and it is should turn the egr off so i took out my false code eliminator out now under wfo it will pull this code some times. I was thinking of puting it back in and see what happens. It did is stock and I cleaned it and once after I put the banks intake in. only twice after taking the false code eliminator out. I dont know if the egr blockoff with the big intake and exhaust would cause it? I dont think the mass air flow censer is bad it could be confused:help

Any one have input on this. I talked to duramax tuners and they told me to send in the ECM and they'll rescale/ turn off the code. But I don't see why it would set the code. It is a 4" intake so no rescaling should have to be done I thought.
